There seem to be quite a few references to the old macro __ARM_NEON__ on the
internet, so I don't think it's a good idea to remove it entirely (at least
yet), but the canonical name does not have the trailing underscores so we
should use that ourselves.

Like GCC, this re-uses the 'f' constraint and a new 'w' print-modifier:
asm ("ldi.w %w0, 1", "=f"(result));
Unlike GCC, the 'w' print-modifer is not _required_ to produce the intended
output. This is a consequence of differences in the internal handling of
the registers in each compiler. To be source-compatible between the
compilers, users must use the 'w' print-modifier.
MSA registers (including control registers) are supported in clobber lists.

Enables the clang driver to begin targeting specific CPUs. Introduced a
"generic" CPU which will ensure that the optional FP feature is enabled
by default when it gets to LLVM, without needing any extra arguments.
Cortex-A53 and A-57 are also introduced with tests, although backend
handling of them does not yet exist.

Although we wire up a bit for v8fp for macro setting
purposes, we don't set a macro yet. Need to ask list
about that.

Adds some Cortex-A53 strings where they were missing before.
Cortex-A57 is entirely new to clang.
Doesn't touch code only used by Darwin, in consequence of which
one of the A53 lines has been removed.

clang front end. This change will allow the __PRFCHW__ macro to be set on these
processors and hence include prfchwintrin.h in x86intrin.h header. Support for
the intrinsic itself seems to have already been added in r178041.

Clang uses UTF-16 and UTF-32 for its char16_t's and char32_t's
exclusively. This means that we can define __STDC_UTF_16__ and
__STDC_UTF_32__ unconditionally.
While there, define __STDC_MB_MIGHT_NEQ_WC__ for FreeBSD. FreeBSD's
wchar_t's don't encode characters as ISO-10646; the encoding depends on
the locale used. Because the character set used might not be a superset
of ASCII, we must define __STDC_MB_MIGHT_NEQ_WC__.

x86 TBM instruction set. Also adding a __TBM__ macro if the TBM feature is
enabled. Otherwise there should be no functionality change to existing features.

A patch to AllocateTarget function to recognize llvm::Triple::NaCl for
MIPSEL and return NaClTargetInfo. Additional test has been added to check
if the expected macros get defined.
llvm-svn: 191124
Intrinsics added shaintrin.h, which is included from x86intrin.h if __SHA__ is
enabled. SHA implies SSE2, which is needed for the __m128i type.
Also add the -msha/-mno-sha option.

address spaces which is both (1) a "semantic" concept and
(2) possibly a hardware level restriction. It is desirable to
be able to discard/merge the LLVM-level address spaces on arguments for which
there is no difference to the current backend while keeping
track of the semantic address spaces in a funciton prototype. To do this
enable addition of the address space into the name-mangling process. Add
some tests to document this behaviour against inadvertent changes.
