[PATCH 14/46] i386: Emulate MMX mmx_eq/mmx_gt3 with SSE

[H.J. Lu]

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): Check TARGET_MMX_INSNS
        instead of TARGET_MMX.
        (*mmx_eq<mode>3): Check TARGET_MMX_INSNS instead of TARGET_MMX.
        Add SSE support.
        (mmx_gt<mode>3): Likewise.
