Thiago Macieira 04bc63f2d6 Add x86 arch detection support for AVX512 and SHA instructions
The flags come from GCC commit 201219:
http://gcc.gnu.org/viewcvs/gcc/branches/avx512/gcc/config/i386/i386-c.c?limit_changes=0&r1=201219&r2=201218&pathrev=201219

Clang and ICC don't seem to have support for this yet.
