util: add AMD CPU family enums and enable L3 cache pinning on Zen3
...
Based on: https://en.wikichip.org/wiki/amd/cpuid
The only reason it's nominated as a fix is because Zen3 might underperform
because the CPU detection ignored it.

util: add auxv based PowerPC AltiVec/VSX detection
...
At least on Linux, we can use the ELF auxiliary vector to
detect the presence of AltiVec, VSX and other CPU features
without having to go through handling SIGILL, which has
various problems of its own.
A similar thing is already being done for ARM to detect NEON.

gallium: Enable ASIMD/NEON on aarch64.
...
NEON (now called ASIMD) is available on all aarch64 CPUs. Our code was
missing an aarch64 path, leading to util_cpu_caps.has_neon always being
false on aarch64.

util: Fix warning in u_cpu_detect on non-x86
...
regs is only set and used on x86; on other platforms (like ARM), this
code causes a trivial warning, solved by moving the regs declaration to
the architecture-dependent usage.
