Reapply Allow system header to provide their own implementation of some
builtin
This reverts commit 3d210ed3d1880c615776b07d1916edb400c245a6.
See https://reviews.llvm.org/D71082 for the patch and discussion that
make it possible to reapply this patch.

Add __warn_memset_zero_len builtin as a workaround for glibc issue
Glibc issue: https://sourceware.org/bugzilla/show_bug.cgi?id=25399 The
fix consist in considering the missing function as a builtin lowered to
a nop.

clang-format: [JS] Handle more keyword-named methods.
Summary: Including `do`, `for`, and `while`, `if`, `else`, `try`,
`catch`, in addition to the previously handled fields. The unit test
explicitly uses methods, but this code path handles both fields and
methods.

Revert "Avoid creating an immutable map in the Automaton class."
This reverts commit 051d330314cb1f175025ca37da8e5e1d851e1790. It broke 
buildbots, for example, 
http://lab.llvm.org:8011/builders/clang-x86_64-debian-fast/builds/21908.

[lldb][NFC] Resynchronize Init/Terminate calls in
SystemInitializerFull/Test.cpp files.
These files should do the more or less the same initialize/terminate
calls in the same order. This just reverts all the differences that have
piled up over time in the SystemInitializerTest that people keep
forgetting about.

[LLD][ELF][ARM][AArch64] Only round up ThunkSection Size when large OS.
In D71281 a fix was put in to round up the size of a ThunkSection to the 
nearest 4KiB when performing errata patching. This fixed a problem with
a very large instrumented program that had thunks and patches mutually 
trigger each other. Unfortunately it triggers an assertion failure in an 
AArch64 allyesconfig build of the kernel. There is a specific assertion 
preventing an InputSectionDescription being larger than 4KiB. This will 
always trigger if there is at least one Thunk needed in that 
InputSectionDescription, which is possible for an allyesconfig build.
Abstractly the problem case is:
.text : {
         *(.text) ;
         ...
         . = ALIGN(SZ_4K);
         __idmap_text_start = .;
         *(.idmap.text)
         __idmap_text_end = .;
         ...
       } The assertion checks that __idmap_text_end - __idmap_start is <
4 KiB. Note that there is more than one InputSectionDescription in the 
OutputSection so we can't just restrict the fix to OutputSections
smaller than 4 KiB.
The fix presented here limits the D71281 to InputSectionDescriptions
that meet the following conditions: 1.) The OutputSection is bigger than
the thunkSectionSpacing so adding thunks will affect the addresses of
following code. 2.) The InputSectionDescription is larger than 4 KiB.
This will prevent any assertion failures that an InputSectionDescription
is < 4 KiB in size.
We do this at ThunkSection creation time as at this point we know that 
the addresses are stable and up to date prior to adding the thunks as 
assignAddresses() will have been called immediately prior to thunk 
generation.
The fix reverts the two tests affected by D71281 to their original state 
as they no longer need the 4KiB size roundup. I've added simpler tests
to check for D71281 when the OutputSection size is larger than the
ThunkSection spacing.

[AArch64][SVE] Add ImmArg property to intrinsics with immediates
Summary: Several SVE intrinsics with immediate arguments (including
those added by D70253 & D70437) do not use the ImmArg property. This
patch adds ImmArg<Op> where required and changes the appropriate
patterns which match the immediates.

[AsmParser] Make generic directives and aliases case insensitive.
GCC will accept any case for assembler directives. For example ".abort"
and ".ABORT" (even ".aBoRt") are equivalent.
https://sourceware.org/binutils/docs/as/Pseudo-Ops.html#Pseudo-Ops
"The names are case insensitive for most targets, and usually written in
lower case."
Change llvm-mc to accept any case for generic directives or aliases of
those directives.
This for Bugzilla #39527.

Fix Wparentheses warning. NFCI.

[SelectionDAG] Better ISD::ANY_EXTEND/ISD::ANY_EXTEND_VECTOR_INREG
ComputeKnownBits support
Add DemandedElts handling to ISD::ANY_EXTEND and add missing
ISD::ANY_EXTEND_VECTOR_INREG handling. Despite the lack of test changes
this code IS being used - its just that the ANY_EXTEND ops are legalized
later on (typically to ZERO_EXTEND equivalents) so we typically manage
to combine later on.

[AArch64][SVE] Add break intrinsics
Summary: Implements the following intrinsics:
    * @llvm.aarch64.sve.brka

   * @llvm.aarch64.sve.brkb
   * @llvm.aarch64.sve.brkb.z
   * @llvm.aarch64.sve.brkn.z
   * @llvm.aarch64.sve.brkpa.z

[lldb] Add missing terminate calls to Python/Lua subsystems

[lldb] Remove out of order OperatingSystemPython::Terminate call in
SystemInitializerFull
We already call it later in the method (which is in the right order as
we Initialize it at the of the constructor).
