i386: Emulate MMX ssse3_ph<plusminus_mnemonic>wv4hi3 with SSE
Emulate MMX ssse3_ph<plusminus_mnemonic>wv4hi3 with SSE by moving bits
64:95 to bits 32:63 in SSE register. Only SSE register source operand
is allowed.
PR target/89021
* config/i386/sse.md (ssse3_ph<plusminus_mnemonic>wv4hi3):
Changed to define_insn_and_split to support SSE emulation.
