Revert "Revert rG6078f2fedcac5797ac39ee5ef3fd7a35ef1202d5 -
"[AArch64][GlobalISel]: Support @llvm.{return,frame}address selection.""
The original change wasn't constraining the operand regclasses which
broke EXPENSIVE_CHECKS.

Commit c75180258e6363a03fc036abaa4c79a14a3f952e by Lang Hames
[ORC] Set setCloneToNewContextOnEmit on LLJIT's transform layer when
needed.
Based on Don Hinton's patch in https://reviews.llvm.org/D72406. This
feature was accidentally left out of
e9e26c01cd865da678b1af6ba5f417c713956a66, and would have pessimized
concurrent compilation in the default case.
Thanks for spotting this Don!

Commit d6a9b7e58967f3d996cc4f9b136f02d99b0b8159 by craig.topper
[Mips] Add FileCheck to a test that just tested for a crash.
I believe the generated code here can suffer from double rounding. So I
wanted to capture the existing codegen so we can make decisions about
how to fix it.

[DWARF] Emit DW_AT_call_return_pc as an address
This reverts D53469, which changed llvm's DWARF emission to emit
DW_AT_call_return_pc as a function-local offset. Such an encoding is not
compatible with post-link block re-ordering tools and isn't standards-
compliant.
In addition to reverting back to the original DW_AT_call_return_pc
encoding, teach lldb how to fix up DW_AT_call_return_pc when the address
comes from an object file pointed-to by a debug map. While doing this I
noticed that lldb's support for tail calls that cross a DSO/object file
boundary wasn't covered, so I added tests for that. This latter case
exercises the newly added return PC fixup.
The dsymutil changes in this patch were originally included in D49887:
the associated test should be sufficient to test DW_AT_call_return_pc
encoding purely on the llvm side.

[mlir] Add shaped container component type interface
Summary:
* Add shaped container type interface which allows infering the shape,
element
type and attribute of shaped container type separately. Show usage by
way of
tensor type inference trait which combines the shape & element type in
infering a tensor type;
- All components need not be specified;
- Attribute is added to allow for layout attribute that was previously
   discussed;
* Expand the test driver to make it easier to test new creation
instances
(adding new operands or ops with attributes or regions would trigger
build
functions/type inference methods);
- The verification part will be moved out of the test and to verify
method
   instead of ops implementing the type inference interface in a follow
up;
* Add MLIRContext as arg to possible to create type for ops without
arguments,
region or location;
* Also move out the section in OpDefinitions doc to separate
ShapeInference doc
where the shape function requirements can be captured;
- Part of this would move to the shape dialect and/or shape dialect ops
be
   included as subsection of this doc;
* Update ODS's variable usage to match camelBack format for builder,
state and arg variables;
- I could have split this out, but I had to make some changes around
   these and the inconsistency bugged me :)

[NFC] Refactor InlineResult for readability
Summary: InlineResult is used both in APIs assessing whether a call site
is inlinable (e.g. llvm::isInlineViable) as well as in the function
inlining utility (llvm::InlineFunction). It means slightly different
things (can/should inlining happen, vs did it happen), and the implicit
casting may introduce ambiguity (casting from 'false' in InlineFunction
will default a message about hight costs, which is incorrect here).
The change renames the type to a more generic name, and disables
implicit constructors.

Commit 288a1436392f1fbee2e647cb057086fe700f9c7e by eric
[libc++] Explicitly enumerate std::string external instantiations -
Attempt 2
  The GCC build failures have been addressed, and the LLDB failures were
fixed by LLDB.
   I have also verified that the apple-clang 9.0 segfault no longer
  occurs.
Original Message:
The external instantiation of std::string is a problem for libc++.
   Additions and removals of inline functions in string can cause ABI
   breakages, including introducing new symbols.
    This patch aims to:
     (1) Make clear which functions are explicitly instatiated.
     (2) Prevent new functions from being accidentally instantiated.
     (3) Allow a migration path for adding or removing functions from
the
     explicit instantiation over time.
    Although this new formulation is uglier, it is preferable from a
   maintainability and readability standpoint because it explicitly
   enumerates the functions we've chosen to expose in our ABI. Changing
   this list is non-trivial and requires thought and planning.
    (3) is achieved by making it possible to control the extern template
declaration
   separately from it's definition. Meaning we could add a new
definition to
   the dylib, wait for it to roll out, then add the extern template
   declaration to the header. Similarly, we could remove existing extern
   template declarations while still keeping the definition to prevent
ABI
   breakages.

This creates an optimized / inlined mempcy up to over 2X faster for
short string assignments. With inlining enabled for operator=,
performance is up to 6X faster.
