Stat cache chaining was implemented for a StatListener in the PTH writer so that
it could write out the stat information to PTH. r348266 removed support for PTH,
and it doesn't seem like there are other uses of stat cache chaining. We can
remove the chaining support.

Replace multiple comparisons of getOS() value with FreeBSD, NetBSD,

Direct getOS() comparisons were left whenever used in switch or switch-

Summary:
Some ASM input constraints (e.g., "i" and "n") require immediate values. At O0,
very few code transformations are performed. So if we cannot resolve to an
immediate when emitting the ASM input we shouldn't delay its processing.

The Darwin targets use `int64_t` and `uint64_t` to define the `int_least64_t`

SSE2 vectorization was added in 2012, but it is 2018 now and I can't
observe any performance boost (testing clang -E [all Sema/* CodeGen/* with proper -I options]) with the existing _mm_movemask_epi8+countTrailingZeros or the following SSE4.2 (compiling with -msse4.2):
__m128i C = _mm_setr_epi8('\r','\n',0,0,0,0,0,0,0,0,0,0,0,0,0,0);
_mm_cmpestri(C, 2, Chunk, 16, _SIDD_UBYTE_OPS | _SIDD_CMP_EQUAL_ANY | _SIDD_POSITIVE_POLARITY | _SIDD_LEAST_SIGNIFICANT)

Also make the constructor of IdentifierInfo private to make sure that
they are only created by IdentifierTable, and move it to the header so
that it can be inlined in IdentifierTable::get and IdentifierTable::getOwn.

As of rev. 268898, clang supports __float128 on SystemZ. This seems to
have been in error. GCC has never supported __float128 on SystemZ,
since the "long double" type on the platform is already IEEE-128. (GCC
only supports __float128 on platforms where "long double" is some other
data type.)
For compatibility reasons this patch removes __float128 on SystemZ
again. The test case is updated accordingly.

the preamble, but the compilation may subsequently getFile(open=true)
for non-preamble includes.

Currently, we only accept clang as the scoped attribute identifier for double square bracket attributes provided by Clang, but this has the potential to conflict with user-defined macros. To help alleviate these concerns, this introduces the _Clang scoped attribute identifier as an alias for clang. It also introduces a warning with a fixit on the off chance someone attempts to use __clang__ as the scoped attribute (which is a predefined compiler identification macro).

This patch should not introduce any behavior changes. It consists of
mostly one of two changes:
1. Replacing fall through comments with the LLVM_FALLTHROUGH macro
2. Inserting 'break' before falling through into a case block consisting
of only 'break'.
We were already using this warning with GCC, but its warning behaves
slightly differently. In this patch, the following differences are
relevant:
1. GCC recognizes comments that say "fall through" as annotations, clang
doesn't
2. GCC doesn't warn on "case N: foo(); default: break;", clang does
3. GCC doesn't warn when the case contains a switch, but falls through
the outer case.
I will enable the warning separately in a follow-up patch so that it can
be cleanly reverted if necessary.

This silences a -Wimplicit-fallthrough warning from clang. GCC does not
appear to warn when the case body ends in a switch.
This is a somewhat surprising but intended fallthrough that I pulled out
from my mechanical patch. The code intends to handle 'Yi' and related
constraints as the 'x' constraint.

Similar to how ICC handles CPU-Dispatch on Windows, this patch uses the
resolver function directly to forward the call to the proper function.
This is not nearly as efficient as IFuncs of course, but is still quite
useful for large functions specifically developed for certain
processors.
This is unfortunately still limited to x86, since it depends on
__builtin_cpu_supports and __builtin_cpu_is, which are x86 builtins.
The naming for the resolver/forwarding function for cpu-dispatch was
taken from ICC's implementation, which uses the unmodified name for this
(no mangling additions). This is possible, since cpu-dispatch uses '.A'
for the 'default' version.
In 'target' multiversioning, this function keeps the '.resolver'
extension in order to keep the default function keeping the default
mangling.

I'm unsure if KNL has this feature, but the backend never thought it did, only clang did. The predefined-arch-macros test lost the check for __RTM__ on KNL when it was removed Skylake CPUs in r344117.
I think we want to drop it from KNL for consistency with Skylake anyway regardless of how we got here.

It appears when initially committing the support for the IBM Z vector
extension language, one critical line was lost, causing the specific
keywords __vector, __bool, and vec_step to not actually be enabled.
(Note that this does not affect "vector" and "bool"!)
Unfortunately, this was not caught by any tests either. (All existing
Z vector tests just use the regular "vector" and "bool" keywords ...)
Fixed by adding the missing line and updating the tests.

This patch moves the virtual file system form clang to llvm so it can be

Concretely the patch:
- Moves VirtualFileSystem.{h|cpp} from clang/Basic to llvm/Support.
- Moves the corresponding unit test from clang to llvm.
- Moves the vfs namespace from clang::vfs to llvm::vfs.
- Formats the lines affected by this change, mostly this is the result of
the added llvm namespace.

Summary:
gcc defines macros such as __code_model_small_ based on the user passed command line flag -mcmodel. clang accepts a flag with the same name and similar effects, but does not generate any macro that the user can use. This cl narrows the gap between gcc and clang behaviour.
However, achieving full compatibility with gcc is not trivial: The set of valid values for mcmodel in gcc and clang are not equal. Also, gcc defines different macros for different architectures. In this cl, we only tackle an easy part of the problem and define the macro only for x64 architecture. When the user does not specify a mcmodel, the macro for small code model is produced, as is the case with gcc.
