Emulate MMX pshufw with SSE. Only SSE register source operand is allowed. PR target/89021 * config/i386/mmx.md (mmx_pshufw): Also check TARGET_MMX and TARGET_MMX_WITH_SSE. (mmx_pshufw_1): Add SSE emulation. (*vec_dupv4hi): Changed to define_insn_and_split and also allow TARGET_MMX_WITH_SSE to support SSE emulation. From-SVN: r271226
