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.

PR target/105052
* config/i386/sse.md (ssse3_ph<plusminus_mnemonic>wv4hi3):
Replace "Yv" with "x".
(ssse3_ph<plusminus_mnemonic>dv2si3): Likewise.
(ssse3_psign<mode>3): Likewise.

(cherry picked from commit 99591cf43fc1da0fb72b3da02ba937ba30bd2bf2)
