The second argument must be a constant, otherwise instruction selection
will fail. always_inline is not enough for isel to always fold
everything away at -O0.
Sadly the overloading turned this into a big macro mess. Fixes PR33212.

AVX512_VPOPCNTDQ is a new feature set that was published by Intel.
The patch represents the Clang side of the addition of six intrinsics for two new machine instructions (vpopcntd and vpopcntq).
It also includes the addition of the new feature set.

- 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.

size_t is usually defined as unsigned long, but on 64-bit platforms,
stdint.h currently defines SIZE_MAX using "ull" (unsigned long long).
Although this is the same width, it doesn't necessarily have the same
alignment or calling convention. It also triggers printf warnings when
using the format flag "%zu" to print SIZE_MAX.
This changes SIZE_MAX to reuse the compiler-provided __SIZE_MAX__, and
provides similar fixes for the other integers:
- INTPTR_MIN
- INTPTR_MAX
- UINTPTR_MAX
- PTRDIFF_MIN
- PTRDIFF_MAX
- INTMAX_MIN
- INTMAX_MAX
- UINTMAX_MAX
- INTMAX_C()
- UINTMAX_C()
... and fixes the typedefs for intptr_t and uintptr_t to use
__INTPTR_TYPE__ and __UINTPTR_TYPE__ instead of int32_t, effectively
reverting r89224, r89226, and r89237 (r89221 already having been
effectively reverted).
We can probably also kill __INTPTR_WIDTH__, __INTMAX_WIDTH__, and
__UINTMAX_WIDTH__ in a follow-up, but I was hesitant to delete all the
per-target CHECK lines in this commit since those might serve their own
purpose.

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}.

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.
