i386: Emulate MMX pshufb with SSE version
Emulate MMX version of pshufb with SSE version by masking out the bit 3
of the shuffle control byte. Only SSE register source operand is allowed.
PR target/89021
* config/i386/sse.md (ssse3_pshufbv8qi3): Changed to
define_insn_and_split. Also allow TARGET_MMX_WITH_SSE. Add
SSE emulation.
