* expr.c (gen_group_rtx, emit_group_move): New functions.

	* expr.h (gen_group_rtx, emit_group_move): Prototype.
	* function.c (expand_function_start): Use gen_group_rtx to create a
	PARALLEL rtx to hold the return value when the real return rtx is a
	PARALLEL.
	(expand_function_end): Use emit_group_move to move the return value
	from a PARALLEL to the real return registers.
	* rtl.h (REG_FUNCTION_VALUE_P): Allow function values to be returned
	in PARALLELs.
