Patch
Trying to compile a function with an "xop" multiversion fails with a "No
dispatcher found for xop" error message. Similarly newer x86 architectures are
not detected.
Patch attached.
Adds support for haswell, silvermount, and the most recent amd models. It also
prioritizes AVX2 versions over AMD specific version pre-AVX2.
