[PATCH 05/42] i386: Emulate MMX mulv4hi3 with SSE

[H.J. Lu]

Emulate MMX mulv4hi3 with SSE.  Only SSE register source operand is
allowed.

        PR target/89021
        * config/i386/mmx.md (mmx_mulv4hi3): Also allow
        TARGET_MMX_WITH_SSE.
        (mulv4hi3): New.
        (*mmx_mulv4hi3): Also allow TARGET_MMX_WITH_SSE.  Add SSE
        support.
