PR middle-end/79788
	PR middle-end/80375
	* c-common.c (c_common_type_for_mode): Don't handle
	widest_*_literal_type_node here.
	c_common_signed_or_unsigned_type): Likewise.
	(c_common_nodes_and_builtins): Set widest_*_literal_type_node
	to *intTI_type_node or *intDI_type_node depending on whether
	TImode is supported by the target or not.

	* gcc.dg/pr79788-1.c: New test.
	* gcc.dg/pr79788-2.c: New test.
