Detect if AVX2 is usable
This patch checks and sets bit_AVX2_Usable in __cpu_features.feature.
* sysdeps/x86_64/multiarch/ifunc-defines.sym (COMMON_CPUID_INDEX_7):
New.
* sysdeps/x86_64/multiarch/init-arch.c (__init_cpu_features):
Check and set bit_AVX2_Usable.
* sysdeps/x86_64/multiarch/init-arch.h (bit_AVX2_Usable): New
macro.
(bit_AVX2): Likewise.
(index_AVX2_Usable): Likewise.
(CPUID_AVX2): Likewise.
(HAS_AVX2): Likewise.
