It's used by MS headers in VS 2017 without including intrin.h, so we
can't implement it in the header anymore.

It seems MS headers have started using __readgsqword, and since it's
used in a header that doesn't include intrin.h, we can't implement it as
an inline function anymore.
That was already the case for __readfsdword, which Saleem added support
for in r220859. This patch reuses that codegen to implement all of
__read[fg]s{byte,word,dword,qword}.

I made some small changes in smmintrin.h and emmintrin.h intrinsics.
- changed some regular comments '//' into doxygen-style comments '///' where necessary
- removed some trailing spaces in doxygen comments.
I got an OK from Eric Christopher to commit doxygen comments without prior code
review upstream.

- Fix a variable naming mismatch
- Fix gcc extension pointer arithmetic on void to cast to char *.
- Test that the header (and htmintrin.h) parse.

The DAZ feature introduces the denormal zero support for x86.
Currently the definitions are located under SSE3 header, however there are some SSE2 targets that support the feature as well.

Removed ndrange_t as Clang builtin type and added

Use type name to do the Sema checking in enqueue_kernel

Prior to OpenCL 2.0, image3d_t can only be used with the write_only
access qualifier when the cl_khr_3d_image_writes extension is enabled,
see e.g. OpenCL 1.1 s6.8b.
Require the extension for write_only image3d_t types and guard uses of
write_only image3d_t in the OpenCL header.

For a << b (as original vec_sl does), if b >= sizeof(a) * 8, the
behavior is undefined. However, Power instructions do define the
behavior, which is equivalent to a << (b % (sizeof(a) * 8)).
This patch changes altivec.h to use a << (b % (sizeof(a) * 8)), to
ensure the consistent semantic of the instructions. Then it combines
the generated multiple instructions back to a single shift.
This patch handles left shift only. Right shift, on the other hand, is
more complicated, considering arithematic/logical right shift.

Added doxygen comments for the newly added intrinsics in avxintrin.h, namely _mm256_cvtsd_f64, _mm256_cvtsi256_si32 and _mm256_cvtss_f32
Added doxygen comments for the new intrinsics in emmintrin.h, namely _mm_loadu_si64 and _mm_load_sd.
Explicit parameter names were added for _mm_clflush and _mm_setcsr
The rest of the changes are editorial, removing trailing spaces at the end of the lines.

Summary:
MSVC seems to use "__in" and "__out" for its own purposes, so we have to

Summary:
These duplicate declarations cause a problem for CUDA compiles on
Windows. All implicitly-defined functions are host+device, and this
applies to the declarations in Builtin.def. But then when we see the
declarations in intrin.h, they have no attributes, so are host-only
functions. This is an error.
(A better fix might be to make these builtins host-only, but that is a
much bigger change.)

According to extended asm syntax, a case where the clobber list includes a variable from the inputs or outputs should be an error - conflict.
for example:
const long double a = 0.0;
int main()
{
char b;
double t1 = a;
__asm__ ("fucompp": "=a" (b) : "u" (t1), "t" (t1) : "cc", "st", "st(1)");
return 0;
}
This should conflict with the output - t1 which is st, and st which is st aswell.
The patch fixes it.
