Remove PUSH_ARGS_REVERSED from the RTL expander.

gcc/

	* calls.c (initialize_argument_information): Always treat
	PUSH_ARGS_REVERSED as 1, simplify code accordingly.
	(expand_call): Likewise.
	(emit_library_call_calue_1): Likewise.
	* expr.c (PUSH_ARGS_REVERSED): Do not define.
	(emit_push_insn): Always treat PUSH_ARGS_REVERSED as 1, simplify
	code accordingly.
