Reverts r289181: it's currently breaking modules using simd.h in
10.12 SDK.
This reverts commit 6e73e3464e96a4e00492c24aa790d36e1adb5702.

This will allow the backend to constant fold these to generic shuffle vectors like 128-bit and 256-bit without having to working about handling masking.

Tagged instruction names with <c> INSTR_NAME </c> to display them in typewriter font.
In the past, \c command was used, unfortunately it applied to only one word.
<c> .. </c> has the same meaning, but applies to all words in between the tags.

Allow darwin to provide additional definitions and implementation
specifc values for tgmath.h on Apple platforms.

Improved doxygen comments for fxsrintrin.h and mmintrin.h intrinsics by taagging parameter names with \a doxygen command to display parameters in italics.
Formatted comments to fit into 80 chars.

Documentation for some of the avxintrin.h's intrinsics errorneously said that
non VEX-prefixed instructions could be generated. This was fixed.
I tried several different solutions to achieve pretty printing of unordered lists (nested and non-nested) in param sections in doxygen.

(commit again after fixing the buildbot failures)
This adds various overloads of the following builtins to altivec.h:
vec_neg
vec_nabs
vec_adde
vec_addec
vec_sube
vec_subec
vec_subc
Note that for vec_sub builtins on 32 bit integers, the semantics is similar to
what ISA describes for instructions like vsubecuq that work on quadwords: the
first operand is added to the one's complement of the second operand. (As
opposed to two's complement which I expected).

The doxygen comments are automatically generated based on Sony's intrinsics docu
ment.
I got an OK from Eric Christopher to commit doxygen comments without prior code
review upstream. This patch was internally reviewed by Charles Li.

Added doxygen comments to avxintrin.h's intrinsics. As of now, all the intrinsics in this file that were documented by Sony's intrinsics guide should have corresponding doxygen comments.
Note: The doxygen comments are automatically generated based on Sony's intrinsic

I made several changes for consistency with the rest of x86 instrinsics header files. Some of these changes help to render doxygen comments better.
1. avxintrin.h – Moved the opening bracket on a separate line for several
intrinsics (for consistency with the rest of the intrinsics).
2. emmintrin.h - Moved the doxygen comment next to the body of the function;
- Added braces after extern "C" even though there is only
one declaration each time
3. xmmintrin.h - Moved the doxygen comment next to the body of the function;
- Added intrinsic prototypes for a couple of macro definitions
into the doxygen comment;
- Added braces after extern "C" even though there is only one
declaration each time
4. ammintrin.h – Removed extra line between the doxygen comment and the body
of the functions (for consistency with the rest of the files).

Both the (V)CVTDQ2PD (i32 to f64) and (V)CVTUDQ2PD (u32 to f64) conversion instructions are lossless and can be safely represented as generic __builtin_convertvector calls instead of x86 intrinsics without affecting final codegen.
This patch removes the clang builtins and their use in the headers - a future patch will deal with removing the llvm intrinsics.
This is an extension patch to D20528 which dealt with the equivalent sse/avx cases.

This patch implements all the overloads for vec_xl_be and vec_xst_be. On BE,
they behaves exactly the same with vec_xl and vec_xst, therefore they are
simply implemented by defining a matching macro. On LE, they are implemented
by defining new builtins and intrinsics. For int/float/long long/double, it
is just a load (lxvw4x/lxvd2x) or store(stxvw4x/stxvd2x). For char/char/short,
we also need some extra shuffling before or after call the builtins to get the
desired BE order. For int128, simply call vec_xl or vec_xst.

Adds 2 vector functions for converting from a vector of unsigned short to a
vector of float. One converts the low 4 halfwords and one converts the high
4 halfwords.

Add vector extract exponent/significand functions to altivec.h, as well as
functions (and related constants) to test the data class of vector float
and vector double.

Added doxygen comments to avxintrin.h's intrinsics. As of now, around 75% of the
intrinsics in this file are documented here. The patches for the other 25% will be se
nt out later.
Removed extra spaces in emmitrin.h.
Note: The doxygen comments are automatically generated based on Sony's intrinsics document.

Certain OpenCL builtin functions are supposed to be executed by all threads in a work group or sub group. Such functions should not be made divergent during transformation. It makes sense to mark them with convergent attribute.
The adding of convergent attribute is based on Ettore Speziale's work and the original proposal and patch can be found at https://www.mail-archive.com/cfe-commits@lists.llvm.org/msg22271.html.

Unfortunately, the backend currently doesn't fold masks into the instructions correctly when they come from these shufflevectors. I'll work on that in a future commit.
