A few (mostly CodeGen) parts of Clang were tightly coupled to the
AArch64 backend. Now that it's gone, they will not even compile.
I've also deduplicated RUN lines in many of the AArch64 tests. This
might improve "make check-all" time noticably: some of those NEON
tests were monsters.

Windows on ARM uses AAPCS, but has some deviations. wchar_t remains an unsigned
short on WoA, which does not conform to AAPCS. Ensure that wchar_t is defined
accordingly.

Summary: The condition in the base class is rather strange. It says a target has the 128-bit integer type if the size of a pointer is >= 64-bits. N32 has 32-bit pointers but 64-bit integers. I'm a bit reluctant to change this for all targets so this patch makes the method virtual and overrides it for MIPS64.

Summary:
Correct size_t to be unsigned int and ptrdiff_t to be signed long. The types were the correct size before this change but
the exact type matters for name mangling and exception handling in C++.

This introduces the definitions needed for the Windows on ARM target. Add
target definitions for both the MSVC environment and the MSVC + Itanium C++ ABI
environment. The Visual Studio definitions correspond to the definitions
provided by Visual Studio 2012.

Visual Studio is the Integrated Development Environment. The toolchain is

per the recommendation of Reid Kleckner.

At least on REL6 (Linux/glibc 2.12), the proper symbol for generating gprof
data is _mcount, not mcount. Prior to this change, compiling with -pg would
generate linking errors (because of unresolved references to mcount), after
this change -pg seems at least minimally functional.

This adds Clang support for the ARM64 backend. There are definitely
still some rough edges, so please bring up any issues you see with
this patch.
As with the LLVM commit though, we think it'll be more useful for
merging with AArch64 from within the tree.

This follows the LLVM change to canonicalise the Windows target triple
spellings. Rather than treating each Windows environment as a single entity,
the environments are now modelled properly as an environment. This is a
mechanical change to convert the triple use to reflect that change.

Additional clarification from Uli for the background on _CALL_ELF:
"Historically GCC has provided various _CALL_... predefines depending on the
ABI currently being compiled for. (_CALL_SYSV,_CALL_AIXDESC, _CALL_DARWIN )
When we needed a new define for the current ABI, we decided on using _CALL_ELF
since the official name of the ABI is the OpenPower ElfV2 ABI, with the
current Linux ABI retro-actively being renamed the ELFv1 ABI
and so we decided on using _CALL_ELF to identify the Linux (+BSD etc.) ELF ABI,
with _CALL_ELF=1 for the v1 ABI and _CALL_ELF=2 for the v2 ABI.
(Note that this matches the gcc compiler switch -mabi=elfv1 vs. -mabi=elfv2)."
In code, a (_CALL_ELF==2) check will indicate when the ELFv2 ABI is
to be used. This is the desired default for the PPC64 LE target.

This adds support for the PPC "wc" inline asm constraint (used for allocating
individual CR bits). Support for this constraint type was recently added to the
LLVM PowerPC backend. Although gcc does not currently support allocating
individual CR bits, this identifier choice has been coordinated with the gcc
PowerPC team, and will be marked as reserved for this purpose in the gcc
constraints.md file.
Prior to this change, none of the multi-character PPC constraints were handled
correctly (the '^' escape character was not being added as required by the
parsing code in LLVM). This should now be fixed. I'll add tests for these other
constraints as support is added for them in the backend.

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++.

Summary:
This removes the need to coerce UnknownABI to the default ABI (O32 for
MIPS32, N64 for MIPS64 [*]) in both MipsSubtarget and MipsAsmParser.
Clang has been updated to disable both possible default ABI's before enabling
the ABI it intends to use.
[*] N64 being the default for MIPS64 is not actually correct.
However N32 is not fully implemented/tested yet.
