Corrected several typos and incorrect parameters description that Sony
's techinical writer found during review.
I got an OK from Eric Christopher to commit doxygen comments without prior code
review upstream.

- I removed doxygen comments for the intrinsics that "alias" the other existing documented intrinsics and that only sligtly differ in spelling (single underscores vs. double underscores).
#define _tzcnt_u16(a) (__tzcnt_u16((a)))
It will be very hard to keep the documentation for these "aliases" in sync with the documentation for the intrinsics they alias to. Out of sync documentation will be more confusing than no documentation.

Improved doxygen comments for the following intrinsics headers: __wmmintrin_pclmul.h, bmiintrin.h, emmintrin.h, f16cintrin.h, immintrin.h, mmintrin.h, pmmintrin.h, tmmintrin.h
Added \n commands to insert a line breaks where necessary, since one long line of documentation is nearly unreadable.
Formatted comments to fit into 80 chars.
In some cases added \a command in front of the parameter names to display them in italics.

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.

Added doxygen comments to avxintrin.h's intrinsics. As of now, only around 50% of the intrinsics in this file are documented here. The patches for the other half will be sent out later.
Updated bmiintrin.h to fix an incorrect section name.
Updated f16cintrin.h to fix incorect parameter names.
The doxygen comments are automatically generated based on Sony's intrinsics document.
I got an OK from Eric Christopher to commit doxygen comments without prior code
review upstream.

The tzcnt intrinsics are used non non-BMI targets by code (e.g. ffmpeg)
that uses it as a potentially faster BSF.
The TZCNT instruction is special in that it's encoded in a
backward-compatible way and behaves as BSF on non-BMI targets.

This involved removing the conditional inclusion and replacing them
with target attributes matching the original conditional inclusion
and checks. The testcase update removes the macro checks for each
file and replaces them with usage of the __target__ attribute, e.g.:
int __attribute__((__target__(("sse3")))) foo(int a) {
_mm_mwait(0, 0);
return 4;
}
This usage does require the enclosing function have the requisite
__target__ attribute for inlining and code generation - also for
any macro intrinsic uses in the enclosing function. There's no change
for existing uses of the intrinsic headers.

This is a precursor to changing them to use the new target attribute
code.

for 0 before calling __builtin_ctz. Without this the optimizers may take advantage of the undefined behavior and produce incorrect results. LLVM itself still needs to be taught to merge the zero check into the llvm.cttz with defined zero behavior.
