Summary:
Libc++ currently implements the `ATOMIC_<TYPE>_LOCK_FREE` macros using the `__GCC_ATOMIC_<TYPE>_LOCK_FREE` macros. However these are not available when MSVC compatibility is enabled even though C11 `_Atomic` is. This prevents libc++ from correctly implementing `ATOMIC_<TYPE>_LOCK_FREE`.
This patch adds an alternative spelling `__CLANG_ATOMIC_<TYPE>_LOCK_FREE` that is enabled with `-fms-compatibility`.

immediate operands.
This commit adds an AArch64 dag-combine that optimizes code generation
for logical instructions taking immediate operands. The optimization
uses demanded bits to change a logical instruction's immediate operand
so that the immediate can be folded into the immediate field of the
instruction.

ObjC++ has two different types of "pointer" types (ObjCClassPointerType
and PointerType). Both can be indirected through. However, the former
is not a member expression. Ensure that we do not try to rebuild the
MRE in that case.

Single-threaded fences aren't required to provide any synchronization with
other processing elements so there's no need for a DMB. They should still be a
barrier for compiler optimizations though.

Sometimes you are debugging in source, but you really only want to see
the disassembly. That's easy to do but you have to set a few variables.
This command toggles between your old values, and a disassembly only mode.

This patch fixes most of the python3 incompatabilities
within git-clang-format while keeping the script python2 compatible.
There is still one remaining incompatability that prevents using Python3
which is the `str` vs `byte` type change. I plan to put those fixes
up for review separately.
This patch contains fixes for the following incompatabilities:
1) Use the new style Python3 `print` function. This requires importing
__future__.print_function.
2) Fix incompatability between the Python3 octal prefix and the
octal prefix Git uses.
3) Replace use of dict.iteritems() with dict.viewitems() because iteritems()
has been removed in Python3. viewitems() reviews python 2.7 but that is
also what the script is documented as requiring.

Summary:
This already appears to be the case in all .cc test files,
it was probably left out of the .c test files accidentally. Make it a global
default, instead of manually adding it to each individual test.
This is needed to force leak detection for Darwin tests, where leak detection
is disabled by default.

Before, we assumed that any ConstantInt offset was precisely the access width,
so we could use the "[rN]!" form. ISelLowering only ever created that kind, but
further simplification during combining could lead to unexpected constants and
incorrect codegen.
Should fix PR32658.

Associate the version-when-defined with definitions of standard DWARF
constants. Identify the "vendor" for DWARF extensions.
Use this information to verify FORMs in .debug_abbrev are defined as
of the DWARF version specified in the associated unit.
Removed two tests that had specified DWARF v1 (which essentially does
not exist).

This change only affects unit tests, but no functional changes are
expected on LLVM-IR, as no Known information is yet extracted and
consequently this functionality is only triggered through unit tests.
