Summary:
This removes the need to pass -mnan=2008 explicitly to be able to compile
the test-suite for MIPS32r6/MIPS64r6.

Add predefined stdint macros that match the given patterns:
U?INT{_,_FAST,_LEAST}{8,16,32,64}_{MAX,TYPE}
U?INT{PTR,MAX}_{MAX,TYPE}

Most 64-bit targets define int64_t as long int, and AArch64 should
make same definition to follow LP64 model. In GNU tool chain, int64_t
is defined as long int for 64-bit target. So to get consistent with GNU,
it's better Changing int64_t from 'long long int' to 'long int',
otherwise clang will get different name mangling suffix compared with g++.

TargetInfo::getSuitableAlign() was introduced in r146762 and is defined
as alignof(std::max_align_t).
Introduce __ALIGNOF_MAX_ALIGN_T__ which exposes getSuitableAlign() so
that libc++ may take advantage of it.

currently, for thumbv8, two predefined macros are missing:
define __THUMB_INTERWORK__ 1
define __THUMB_INTERWORK__ 1
This patch adds them for thumbv8.

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__.

This patch adds -mmsa and -mno-msa to the options supported by
clang to enable and disable support for MSA.
When MSA is enabled, a predefined macro '__mips_msa' is defined to 1.

This patch provides basic support for powerpc64le as an LLVM target.
However, use of this target will not actually generate little-endian
code. Instead, use of the target will cause the correct little-endian
built-in defines to be generated, so that code that tests for
__LITTLE_ENDIAN__, for example, will be correctly parsed for
syntax-only testing. Code generation will otherwise be the same as
powerpc64 (big-endian), for now.
The patch leaves open the possibility of creating a little-endian
PowerPC64 back end, but there is no immediate intent to create such a
thing.
The new test case variant ensures that correct built-in defines for
little-endian code are generated.

this code. These aren't technically standard predefines for the platform
but apparantly lots of folks use them as they show up within LLVM's own
codebase. ;] This may even fix some self host issues w/ the JIT!!!

Add __has_feature and __has_extension checks for C++1y features (based on the provisional names from
the C++ features study group), and update documentation to match.

This patch then adds all the usual platform-specific pieces for SystemZ:
driver support, basic target info, register names and constraints,
ABI info and vararg support. It also adds new tests to verify pre-defined
macros and inline asm, and updates a test for the minimum alignment change.
This version of the patch incorporates feedback from reviews by
Eric Christopher and John McCall. Thanks to all reviewers!

This adds a test to make sure we define _WCHAR_T_DEFINED and
_NATIVE_WCHAR_T_DEFINED correctly in the preprocessor, and updates
stddef.h to set it when typedeffing wchar_t.
