i386: Rename patterns for vec_widen_<s>mult_even/odd_<mode>

        * config/i386/sse.md (vec_widen_umult_even_v8si): Rename from
        avx2_umulv4siv4di3.
        (vec_widen_umult_even_v4si): Rename from sse2_umulv2siv2di3.
        (vec_widen_smult_even_v8si): Rename from avx2_mulv4siv4di3.
        (mulv4si3): Remove XOP test shadowed by SSE4 test.
        * config/i386/i386.c (bdesc_args): Update pattern names.
        (ix86_expand_sse2_mulvxdi3): Likewise.
        (ix86_expand_mul_widen_evenodd): Likewise.  Remove XOP test
        shadowed by SSE4 test.
