    x86: Use x constraint on SSSE3 patterns with MMX operands

    Since PHADDW/PHADDD/PHADDSW/PHSUBW/PHSUBD/PHSUBSW/PSIGNB/PSIGNW/PSIGND
    have no AVX512 version, replace the "Yv" register constraint with the
    "x" register constraint.

            * config/i386/sse.md (ssse3_ph<plusminus_mnemonic>wv4hi3):
            Replace "Yv" with "x".
            (ssse3_ph<plusminus_mnemonic>dv2si3): Likewise.
            (ssse3_psign<mode>3): Likewise.
