i386: Emulate MMX mmx_eq/mmx_gt<mode>3 with SSE

Emulate MMX mmx_eq/mmx_gt<mode>3 with SSE.  Only SSE register source
operand is allowed.

        PR target/89021
        * config/i386/mmx.md (mmx_eq<mode>3): Also allow
        TARGET_MMX_WITH_SSE.
        (*mmx_eq<mode>3): Also allow TARGET_MMX_WITH_SSE.  Add SSE
        support.
        (mmx_gt<mode>3): Likewise.
