128-bit vector integer sign extensions correctly lower to the pmovsx instructions even for debug builds.
This patch removes the builtins and reimplements the _mm_cvtepi*_epi* intrinsics __using builtin_shufflevector (to extract the bottom most subvector) and __builtin_convertvector (to actually perform the sign extension).

If an import directive was put into wrong context, the error message was obscure,
complaining on misbalanced braces. To get more descriptive messages, annotation
tokens related to modules are processed where they must not be seen.

Use an enumeration for the Floating Point ABIs supported on MIPS. This is
replicating the ARM change to avoid string based tracking of the floating point
ABI. NFC.

Binary literals predate C++14, but they are listed as a C++14 extension since
this was the first time they were standardized in the language. Move the
warning into a subgroup so it can be selectively disabled when checking for
other C++14 features.

Summary:
Name `Out` refers to the parameter. It is moved into the member `Out`
in ctor-init. Dereferencing null pointer will crash clang, if user
passes '-analyzer-viz-egraph-ubigraph' argument.

Generation of clang symlinks now uses add_clang_symlink macro which uses add_llvm_symlink. Also the list of symlinks to generate is configurable via CLANG_LINKS_TO_CREATE.
This re-lands r248015, with fixes for clang symlinks to always be generated as part of the clang and install-clang targets.
llvm-svn: 248043
The signature may not have been computed at the time the module reference
is generated (e.g.: in the future while emitting debug info for a clang
module). Using the full module name is safe because each clang module may
only have a single definition.

LLVM r217812 made it so that clang-cl implicitly creates bigobj files when
needed, independent of this flag. It looks like cl has this flag to produce obj
flags compatible with MSVS 2003's linker by default, something we don't care
about. Since clang-cl always has /bigobj behavior, don't warn that the flag is
unused, just ignore it silently.

The problem this time was the /clang matching the InstalledDir line.
Now we just use regular expressions which are more flexible, if a bit less
readable, than CHECK+CHECK-SAME.
llvm-svn: 248031
CHECK-LABEL assumes that there is only one occurrence of the match.
The output looks like:
clang version 3.8.0 (trunk 247999)
....
/path/to/build/dir/bin/clang-3.8 ....
If the path contains lld, the second CHECK-LABEL matches it and we fail since
there is no -cc1as between clang and lld.

Use an enumeration and change the use of the FloatABI from a string to the
enumeration. This avoids the use of string values to represent an enumeration.

Summary:
This change adds support for `__builtin_ms_va_list`, a GCC extension for
variadic `ms_abi` functions. The existing `__builtin_va_list` support is
inadequate for this because `va_list` is defined differently in the Win64
ABI vs. the System V/AMD64 ABI.
Depends on D1622.
