Split out host/bufferiszero.h.inc for x86, aarch64 and generic
in order to avoid an overlong ifdef ladder.

QEMU now requires an x86-64-v2 host, which has the POPCNT instruction.
Use it freely in TCG-generated code.

The only user was the SSE4.1 variant of buffer_is_zero, which has
been removed; code to compute CPUINFO_SSE4 is dead.

Add cpuinfo.h for i386 and x86_64, and the initialization
for that in util/. Populate that with a slightly altered

will be adjusted one patch at a time.
