Roughly. instead of 4 loads and 8 multiples, use 1 load and 2 multiples
4 times over. The original code, as with the C code from clang and gcc,
did all the loads, then all the math, then the store. The new code
does a load, then the math, then the next load, etc.
This schedules better on current arm 64 cpus.
Number of registers also reduced, reusing the same registers.

In cross builds of chrome/win, the host and target toolchains currently
have the same name. To fix this, rename clang_x64 to win_clang_x64.
Because the toolchain name is also referenced in libyuv, this requires
a five-sided change:
1. Introduce variable containing the toolchain name in src.git
2. Change libyuv to refer to the variable
3. Rename toolchain in src.git (including in the newly introduced var)
4* Let libyuv refer to the new name directly
5. Remove variable again

The CpuId function is a wrapper for the intrinsic, or
implemented with inline if unavailable. It had been
using uint32, but the intrinsics use int, so it was causing
casting and lint warnings. This change makes the internal
implementation use int.
Casting was also done for xgetbv, and the cast is simply
removed, and is not causing a build error.
MipCpuCaps was doing strlen to check for white space after the
instruction set. Arm also does this but with a hard coded offset.
This was causing a cast from size_t to int, which produced a lint
warning. The change removes the white space detect.
In theory the code could be used to detect SSE vs SSE2, and it would
need to check SSE is followed by a space or end of line. But this
code is only used on Arm and Mips, where there there is one form
of SIMD detected. e.g. MSA for mips. If a new instruction set is
added with a similar name, the write space check could be reintroduced.
But its more likely the code can be rewritten to use a better form
of detection by then. Or remove detection and require the instructions
