Log:
	* config/rx/rx.c (rx_function_arg_boundary): When using the RX ABI
	align stack arguments to their natural alignment.
	(rx_narrow_volatile_bitfield): New function.  Allows narrow
	volatile bitfields.
	(rx_ok_to_inline): New function.  Do not inline functions with
	local variables into a naked caller.
	(TARGET_NARROW_VOLATILE_BITFIELD): Define.
	(TARGET_CAN_INLINE_P): Define.
	* config/rx/rx.c (TARGET_CPU_CPP_BUILTINS): Define __RX_ABI__ or
	__RX_GC_ABI__.
	(ASM_SPEC): Pass -mgcc-abi on to the assembler.
	(STRICT_ALIGNMENT): Set to false.
	(CTORS_SECTION_ASM_OP): Add executable attribute.
	(DTORS_SECTION_ASM_OP): Add executable attribute.
	(INIT_ARRAY_SECTION_ASM_OP): Add executable attribute.
	(FINI_ARRAY_SECTION_ASM_OP): Add executable attribute.
	* config/rx/rx.md (subdi3): Don't allow MEMs as the third operand,
	as it causes too much reload pressure.
	* config/rx/rx.opt (mgcc-abi): New option.
	(mrx-abi): New option.
	* config/rx/t-rx (MULTILIB_OPTIONS): Show how to add an ABI
	multilib.
	(MULTILIB_DIRNAMES): Likewise.
