Add ifunc tests for x86_64 memset_chk and memset
This patch adds ifunc tests for x86_64 memset_chk and memset. It also defines HAS_AVX2 with AVX2_Usable since AVX2 may not be usable even if processor has AVX2. * sysdeps/x86_64/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list): Add tests for memset_chk and memset. * sysdeps/x86_64/multiarch/init-arch.h (HAS_AVX2): Defined with AVX2_Usable.
