* mips.c (function_prologue): When TARGET_MIPS16, adjust the register
	offset in the .mask pseudo to compensate for frame pointer adjustments.
	(mips16_fp_args, build_mips16_call_stub): For little endian, do not
	word swap arguments moved to/from FP registers.
	* mips16.S (DFREVCMP): Reverse arguments to OPCODE.
