This change splits the _LIBCPP_STRING_EXTERN_TEMPLATE_LIST up into a _LIBCPP_STRING_V1_EXTERN_TEMPLATE_LIST containing the stable ABI, and a _LIBCPP_STRING_UNSTABLE_EXTERN_TEMPLATE_LIST containing the unstable ABI.
The purpose is to explicitly define and maintain the two lists, where the unstable ABI allows for ABI breaking changes for purposes such as optimization while offering a strong guarantee that any change inside the unstable ABI does not affect the stable ABI.
As per the comment in the __string header, we do still allow etries to be added to the stable ABI list as the c++ versions and corresponding c++ std API changes.
The OSX_ARCHITECTURES property is supposed to add the -arch flag when
targeting Apple platforms. However, due to a bug in CMake
(https://github.com/Kitware/CMake/blob/master/Source/cmLocalGenerator.cxx#L1780),
this does not apply to assembly files. This results in a linker error
when trying to build libunwind for i386 on MacOS.

VK1 was being used as the output of the copy to regclass, but it
should be VK2/VK4. Shouldn't matter in practice though since
VK1/VK2/VK4/VK8/VK16 are all identicaly and just have different VTs.
Summary: DenseElementsAttr is used to store tensor data, which in some cases can become extremely large(100s of mb). In these cases it is much more efficient to format the data as a string of hex values instead.

This fixes test failures caused by a change to the name of the main
dylib, now called 'main'. It also hardens the engine against potential
future changes to the name.
Summary:
This implements the last step for lowering vector.contract progressively
to LLVM IR (except for masks). Multi-dimensional reductions that remain
after expanding all parallel dimensions are lowered into into simpler
vector.contract operations until a trivial 1-dim reduction remains.

For tracked globals that are unknown after solving, we expect all
non-store uses to be replaced.
This is a follow-up to f8045b250d, which removed forcedconstant.
We should not mark unknown loads as overdefined, as they either load
from an unknown pointer or an undef global. Restore the original logic
for loads.
This includes both GEPs where the indexed type is a scalable vector, and
GEPs where the result type is a scalable vector.

Similar to the rest of the command line that is recorded, the program
path must also have spaces and backslashes escaped. Without this
parsing the recorded command line becomes hard on platforms like
Windows where spaces and backslashes are common.

Summary:
AIX supports both 32-bit and 64-bit environments (with 32-bit being the default). This patch improves support for building LLVM on AIX in both 32-bit and 64-bit mode.
- Change host detection to return correct 32/64-bit triple as config_guess does not return the correct version on 64-bit. This can confuse JIT tests and other things that care about what the host triple is.
- Remove manual setting of 64-bit flags on AIX. AIX provides OBJECT_MODE environment variable to enable the user to obtain a 64-bit development environment. CMake will properly set these flags provided the user sets the correct OBJECT_MODE before configuring and setting them manually will interfere with 32-bit builds.
- Don't present the LLVM_BUILD_32_BITS option on AIX, users should use OBJECT_MODE when running CMake instead.

When analyzing PHIs, we gather the known bits for every operand and
merge them together to get the known bits of the result of the PHI.
It is not unusual that merging the information leads to know nothing
on the result (e.g., phi a: i8 3, b: i8 unknown, ..., after looking at the
second argument we know we will know nothing on the result), thus, as
soon as we reach that state, stop analyzing the following operand (i.e.,
on the previous example, we won't process anything after looking at `b`).
This improves compile time in particular with PHIs with a large number
of operands.

Summary:
D51664 introduces a new structure BasicBlockBits which it expects to be
packed a certain way. This change is very similar to D60164, and we apply the
same fix:
"On AIX, the canonical layout of bit-fields would cause
these ... to span four bytes. Applying the pack pragma for compilers that
employ the AIX canonical layout allows these ... to fit within the expected
two bytes. In the future, the pragma would also likely need to be applied when
building with Clang on AIX."

Summary:
The current structure suffers from several problems, but the main one is that a construction failure is impossible to debug when using the 'get' methods. This is because we only optionally emit errors, so there is no context given to the user about the problem. This revision restructures this so that errors are always emitted, and the 'get' methods simply pass in an UnknownLoc to emit to. This allows for removing usages of the more constrained "emitOptionalLoc", as well as removing the need for the context parameter.
