        * config/i386/i386.c (ix86_function_arg_regno_p): Add MMX_REGNO_P
        for TARGET_MMX.  Use MMX_REGPARM_MAX and SSE_REGPARM_MAX for MMX
        and SSE registers to determine if regno is valid.
        (ix86_function_value_regno_p): Depend FIRST_FLOAT_REG on
        TARGET_FLOAT_RETURNS_IN_80387 also for TARGET_64BIT. Clean up.
