x86: Add FEATURE_AVX512VP2INTERSECT and update GFNI check
Add FEATURE_AVX512VP2INTERSECT to libgcc so that enum processor_features
in libgcc matches enum processor_features in i386-builtins.c. Update
GFNI check to support processors with SSE and AVX versions of GFNI.

* config/i386/cpuinfo.c (get_available_features): Fix
FEATURE_GFNI check. Also check FEATURE_AVX512VP2INTERSECT.
* config/i386/cpuinfo.h (processor_features): Add
FEATURE_AVX512VP2INTERSECT.
