	X86_64_COMPLEX_X87_CLASS.
	(x86_64_reg_class_names): Add name for X86_64_COMPLEX_X87_CLASS.
	(merge_classes): Handle X86_64_COMPLEX_X87_CLASS.
	(classify_argument): XCmode is X86_64_COMPLEX_X87_CLASS.
	(examine_argument): X86_64_COMPLEX_X87_CLASS requires two
	registers when dealing with a return value.
	(construct_container): Handle X86_64_COMPLEX_X87_CLASS.
