i386: Delete the vec_extract_even/odd patterns.

These can be generated by vec_perm_const now.  We could keep the
patterns around, as technically it may be less work, but this
exercises a code path needed by less primary platforms.

        * config/i386/sse.md (VEC_EXTRACT_EVENODD_MODE): Remove.
        (vec_extract_even<mode>, vec_extract_odd<mode>): Remove.
