[libc++] Allow building without threads in standalone builds

Setting _LIBCPP_HAS_NO_THREADS is needed when building libcxxabi without
threads in standalone mode. This is useful when target WASM. Otherwise,
you get an error like "No thread API" when building libcxxabi.

It would be better to link against a properly-configured libc++ headers
CMake target when building libc++abi instead, but we don't generate such
targets yet.

[lld][WebAssembly] Fix --export-all when __stack_pointer is present

With https://reviews.llvm.org/D87537 we made it an error
to import or export a mutable global with the +mutable-globals
feature present.  However the scan was of the entire symbol
table rather than just the imports or exports and the filter
didn't match exaclyt meaning the `__stack_pointer` (a mutable
global) was always triggering with error when the `--export-all`
flag was used.

This also revealed that we didn't have any test coverage for
the `--export-all` flag.

This change fixes the current breakage on the emscripten-releases

[llvm-readobj/elf] - Don't crash when the size of s dynamic symbol table, inferred from the hash table, is broken.

Currently we might derive the dynamic symbol table size from the DT_HASH hash table (using its `nchain` field).
It is possible to crash dumpers with a broken relocation that refers to a symbol with an index
that is too large. To trigger it, the inferred size of the dynamic symbol table should go past the end of the object.

This patch adds a size validation + warning.

[libc++] Use allocator_traits to consistently allocate/deallocate/construct/destroy objects in std::any

https://llvm.org/PR45099 notes (correctly) that we're inconsistent in memory
allocation in `std::any`. We allocate memory with `std::allocator<T>::allocate`,
construct with placement new, destroy by calling the destructor directly, and
deallocate by calling `delete`. Most of those are customizable by the user,
but in different ways.

The standard is silent on how these things are to be accomplished.
This patch makes it so we use `allocator_traits<allocator<T>>` for all
of these operations (allocate, construct, destruct, deallocate).
This is, at least, consistent.

[X86][AVX] lowerShuffleWithSHUFPS - handle missed canonicalization cases.

PR47534 exposes a case where calling lowerShuffleWithSHUFPS directly from a derived repeated mask (found by is128BitLaneRepeatedShuffleMask) results in us using an non-canonicalized mask.

The missed canonicalization in this case is trivial - just commute the mask so we have more (swapped) LHS than RHS references so lowerShuffleWithSHUFPS can handle it.

[lldb] Add -l/--language option to script command

Make it possible to run the script command with a different language
than currently selected.

  $ ./bin/lldb -l python
  (lldb) script -l lua
  >>> io.stdout:write("Hello, World!\n")
  Hello, World!

When passing the language option and a raw command, you need to separate
the flag from the script code with --.

  $ ./bin/lldb -l python
  (lldb) script -l lua -- io.stdout:write("Hello, World!\n")
  Hello, World!

[VectorCombine] Don't vectorize scalar load under asan/hwasan/memtag/tsan

Similar to the tsan suppression in
`Utils/VNCoercion.cpp:getLoadLoadClobberFullWidthSize` (rL175034; load widening used by GVN),
the D81766 optimization should be suppressed under tsan due to potential
spurious data race reports:

  struct A {
    int i;
    const short s; // the load cannot be vectorized because
    int modify;    // it overlaps with bytes being concurrently modified
    long pad1, pad2;
  // __tsan_read16 does not know that some bytes are undef and accessing is safe

Similarly, under asan, users can mark memory regions with
`__asan_poison_memory_region`. A widened load can lead to a spurious
use-after-poison error. hwasan/memtag should be similarly suppressed.

`mustSuppressSpeculation` suppresses asan/hwasan/tsan but not memtag, so
we need to exclude memtag in `vectorizeLoadInsert`.

Note, memtag suppression can be relaxed if the load is aligned to the
its granule (usually 16), but that is out of scope of this patch.

The test case has a check line for the option on a line that includes
the string lld surrounded by any characters. This causes failures
when said string is in the build path. What the test case presumably
means to test is the actual invocation of the LLD linker (i.e. a
linker that has that string as a suffix). This patch simply removes

[OPENMP]Add support for allocate vars in untied tasks.

Local vars, marked with pragma allocate, mustbe allocate by the call of
the runtime function and cannot be allocated as other local variables.
Instead, we allocate a space for the pointer in private record and store
the address, returned by kmpc_alloc call in this pointer.
So, for untied tasks

#pragma omp task untied
   S s;
    #pragma omp allocate(s) allocator(allocator)
   s = x;
compiler generates something like this:
struct task_with_privates {
  S *ptr;

void entry(task_with_privates *p) {
  S *s = p->s;
  switch(partid) {
  case 1:
    p->s = (S*)kmpc_alloc();
    br exit;
  case 2:
    *s = x;
    br exit;
  case 2:
    br exit;

[ConstraintElimination] Add constraint elimination pass.

This patch is a first draft of a new pass that adds a more flexible way
to eliminate compares based on more complex constraints collected from
dominating conditions.

In particular, it aims at simplifying conditions of the forms below
using a forward propagation approach, rather than instcomine-style
ad-hoc backwards walking of def-use chains.

    if (x < y)
      if (y < z)
        if (x < z) <- simplify


    if (x + 2 < y)
        if (x + 1 < y) <- simplify assuming no wraps

The general approach is to collect conditions and blocks, sort them by
dominance and then iterate over the sorted list. Conditions are turned
into a linear inequality and add it to a system containing the linear
inequalities that hold on entry to the block. For blocks, we check each
compare against the system and see if it is implied by the constraints
in the system.

We also keep a stack of processed conditions and remove conditions from
the stack and the constraint system once they go out-of-scope (= do not
dominate the current block any longer).

Currently there still are the least the following areas for improvements

* Currently large unsigned constants cannot be added to the system
  (coefficients must be represented as integers)
* The way constraints are managed currently is not very optimized.

Fix .debug_aranges parsing.

Code was added that used llvm error checking to parse .debug_aranges, but the error check after parsing the DWARFDebugArangesSet was reversed and was causing no error to be returned with no valid address ranges being actually used. This meant we always would fall back onto creating out own address ranges by parsing the compile unit's ranges. This was causing problems for cases where the DW_TAG_compile_unit had a single address range by using a DW_AT_low_pc and DW_AT_high_pc attribute pair (not using a DW_AT_ranges attribute), but the .debug_aranges had correct split ranges. In this case we would end up using the single range for the compile unit that encompassed all of the ranges from the .debug_aranges section and would cause address resolving issues in LLDB where address lookups would fail for certain addresses.

[TSAN] Handle musttail call properly in EscapeEnumerator (and TSAN)

Call instructions with musttail tag must be optimized as a tailcall, otherwise could lead to incorrect program behavior.
When TSAN is instrumenting functions, it broke the contract by adding a call to the tsan exit function inbetween the musttail call and return instruction, and also inserted exception handling code.
This happend throguh EscapeEnumerator, which adds exception handling code and returns ret instructions as the place to insert instrumentation calls.
This becomes especially problematic for coroutines, because coroutines rely on tail calls to do symmetric transfers properly.
To fix this, this patch moves the location to insert instrumentation calls prior to the musttail call for ret instructions that are following musttail calls, and also does not handle exception for musttail calls.

[BFI] Make BFI information available through loop passes inside LoopStandardAnalysisResults

~~D65060 uncovered that trying to use BFI in loop passes can lead to non-deterministic behavior when blocks are re-used while retaining old BFI data.~~

~~To make sure BFI is preserved through loop passes a Value Handle (VH) callback is registered on blocks themselves. When a block is freed it now also wipes out the accompanying BFI entry such that stale BFI data can no longer persist resolving the determinism issue. ~~

~~An optimistic approach would be to incrementally update BFI information throughout the loop passes rather than only invalidating them on removed blocks. The issues with that are:~~
~~1. It is not clear how BFI information should be incrementally updated: If a block is duplicated does its BFI information come with? How about if it's split/modified/moved around? ~~
~~2. Assuming we can address these problems the implementation here will be a massive undertaking. ~~

~~There's a known need of BFI in LICM analysis which requires correct but not incrementally updated BFI data. A follow-up change can register BFI in all loop passes so this preserved but potentially lossy data is available to any loop pass that wants it.~~

See: D75341 for an identical implementation of preserving BFI via VH callbacks. The previous statements do still apply but this change no longer has to be in this diff because it's already upstream 😄 .

This diff also moves BFI to be a part of LoopStandardAnalysisResults since the previous method using getCachedResults now (correctly!) statically asserts (D72893) that this data isn't static through the loop passes.

[CGSCC][NewPM] Fix adding mutually recursive new functions

When adding a new function via addNewFunctionIntoRefSCC(), it creates a
new node and immediately populates the edges. Since populateSlow() calls
G->get() on all referenced functions, it will create a node (but not
populate it) for functions that haven't yet been added. If we add two
mutually recursive functions, the assert that the node should never have
been created will fire when the second function is added. So here we
remove that assert since the node may have already been created (but not
yet populated).

createNode() is only called from addNewFunctionInto{,Ref}SCC().

[AArch64][GlobalISel] Refactor + improve CMN, ADDS, and ADD emit functions

These functions were extremely similar:

- `emitADD`
- `emitADDS`
- `emitCMN`

Refactor them a little, introducing a more generic `emitInstr` function to
do most of the work.

Also add support for the immediate + shifted register addressing modes in each
of them.

Update select-uaddo.mir to show that selecing ADDS now supports folding
immediates + shifts. (I don't think this can impact CMN, because the CMN checks
require a G_SUB with a non-constant on the RHS.)

This is around a 0.02% code size improvement on CTMark at -O3.

[LICM] Make Loop ICM profile aware again

D65060 was reverted because it introduced non-determinism by using BFI counts from already freed blocks. The parent of this revision fixes that by using a VH callback on blocks to prevent this from happening and makes sure BFI data is passed correctly in LoopStandardAnalysisResults.

This re-introduces the previous optimization of using BFI data to prevent LICM from hoisting/sinking if the instruction will end up moving to a colder block.

Internally at Facebook this change results in a ~7% win in a CPU related metric in one of our big services by preventing hoisting cold code into a hot pre-header like the added test case demonstrates.
