trans.c (gigi): Call build_function_type_list instead of build_function_type.

* gcc-interface/trans.c (gigi): Call build_function_type_list instead
	of build_function_type.  Adjust calls to...
	(build_raise_check): ...this.  Do not take a void_tree parameter.
	Call build_function_type_list instead of build_function_type.
	Fix head comment and swap couple of conditional blocks.
