util: Introduce include/qemu/cpuid.h
Clang 3.9 passes the CONFIG_AVX2_OPT configure test. However, the supplied <cpuid.h> does not contain the bit_AVX2 define that we use when detecting whether the routine can be enabled. Introduce a qemu-specific header that uses the compiler's definition of __cpuid et al, but supplies any missing bit_* definitions needed. This avoids introducing any extra ifdefs to util/bufferiszero.c, and allows quite a few to be removed from tcg/i386/tcg-target.inc.c.
