Unwind: remove unnecessary check
Linux/GNU on AArch64 EH ABI Level III is implemented using exception frame
tables as defined in LSB II.11.6. The exception frame tables use the DWARF
Exception Header Encoding as described in LSB II.11.5.1. We already defined the
appropriate definition _LIBUNWIND_SUPPORT_DWARF_UNWIND to enable this.

Unwind: tweak register handling for AArch64
AArch64 uses // as the comment character (although, Darwin uses ;). However,
since we are using the C preprocessor on these files, // can be used as the

Tweak the platform guard to recognise __aarch64__ as well as __arm64__ for the
platform identifier.

Reapply r231508 "CodeGen: Emit constant temporaries into read-only globals."
I disabled putting the new global into the same COMDAT as the function for now.
There's a fundamental problem when we inline references to the global but still
have the global in a COMDAT linked to the inlined function. Since this is only
an optimization there may be other versions of the COMDAT around that are
missing the new global and hell breaks loose at link time.
I hope the chromium build doesn't break this time :)

[DAGCombiner] Fix wrong folding of AND dag nodes.
This patch fixes the logic in the DAGCombiner that folds an AND node according
to rule: (and (X (load V)), C) -> (X (load V))
An AND between a vector load 'X' and a constant build_vector 'C' can be folded
into the load itself only if we can prove that the AND operation is redundant.
The algorithm implemented by 'visitAND' firstly computes the splat value 'S'
from C, and then checks if S has the lower 'B' bits set (where B is the size in
bits of the vector element type). The algorithm takes into account also the
'undef' bits in the splat mask.
Unfortunately, the algorithm only worked under the assumption that the size of S
is a multiple of the vector element type. With this patch, we conservatively
avoid folding the AND if the splat bits are not compatible with the vector
element type.
Added X86 test and-load-fold.ll

Much like we silence warnings about -flto in many cases to facilitate
simplicity in build systems, silence '-stdlib=libc++' when linking. Even
if we're not linking C++ code per-se, we may be passing this flag so
that when we are linking C++ code we pick up the desired standard
library. While most build systems already provide separate C and C++
compile flags, many conflate link flags. Sadly, CMake is among them
causing this warning in a libc++ selfhost.
