i386.md (movsf_push, movsf_mem): Remove.

        * i386.md (movsf_push, movsf_mem): Remove.
        (movsf_push): Rename from movsf_push_nomove and move in front of
        movsf.  Use nonmemory_operand predicate and don't bother checking
        TARGET_MOVE.
        (movsf_push_memory): New pattern.
        (movsf): Don't bother checking for push_operand.  If TARGET_MOVE and
        both operands refer to memory then force operand[1] into a register.
        (movsf_normal): Change to unnamed pattern.
        Likewise for movdf, movxf, and friends.
