Previously, these were always included -- after this change, you have to
#include <new>, which is consistent with how things ought to work.

Summary: The preserved input should be the first argument and the vector inputs should be in the same order as the intrinsics it is used to implement.

Committed after LGTM and check-all
Vector-reduction arithmetic accepts vectors as inputs and produces scalars as outputs.
This class of vector operation forms the basis of many scientific computations.
In vector-reduction arithmetic, the evaluation off is independent of the order of the input elements of V.
Used bisection method. At each step, we partition the vector with previous
step in half, and the operation is performed on its two halves.
This takes log2(n) steps where n is the number of elements in the vector.

With this patch, all intrinsics in this file (with an exception of a handful of a recently added ones) will be documented. I will send out a patch for 4 missining intrisics later.
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. This patch was internally reviewed by Yunzhong Gao.

Summary: We need `__stosb` to be an intrinsic, because SecureZeroMemory function uses it without including intrin.h. Implementing it as a volatile memset is not consistent with MSDN specification, but it gives us target-independent IR while keeping the most important properties of `__stosb`.

Summary: Previously global 64-bit versions of _Interlocked functions broke buildbots on i386, so now I'm adding them as builtins for x86-64 and ARM only (should they be also on AArch64? I had problems with testing it for AArch64, so I left it)

Summary: _BitScan intrinsics (and some others, for example _Interlocked and _bittest) are supposed to work on both ARM and x86. This is an attempt to isolate them, avoiding repeating their code or writing separate function for each builtin.

These were reverted in r283753 and r283747.
The first patch added a header to the root 'Headers' install directory,
instead of into 'Headers/cuda_wrappers'. This was fixed in the second
patch, but by then the damage was done: The bad header stayed in the
'Headers' directory, continuing to break the build.
We reverted both patches in an attempt to fix things, but that still
didn't get rid of the header, so the Windows boostrap build remained
broken.
It's probably worth fixing up our cmake logic to remove things from the
install dirs, but in the meantime, re-land these patches, since we
believe they no longer have this bug.

Summary:
Currently we declare our inline __device__ math functions in namespace
std. But libstdc++ and libc++ declare these functions in an inline
namespace inside namespace std. We need to match this because, in a
later patch, we want to get e.g. <complex> to use our device overloads,
and it only will if those overloads are in the right inline namespace.

Summary: We need x86-64-specific builtins if we want to implement some of the MS intrinsics - winnt.h contains definitions of some functions for i386, but not for x86-64 (for example _InterlockedOr64), which means that we cannot treat them as builtins for both i386 and x86-64, because then we have definitions of builtin functions in winnt.h on i386.

This patch corresponds to review:

It adds the __POWER9_VECTOR__ macro and the -mpower9-vector option along with
a number of altivec.h functions (refer to the code review for a list).

On ARM, there are multiple versions of each of the intrinsics, with
acquire/relaxed/release barrier semantics.
The newly added ones are provided as inline functions here instead of builtins,
since they should only be available on certain archs (arm/aarch64).
This is necessary in order to compile C++ code for ARM in MSVC mode.
