	PR middle-end/29719
	PR middle-end/31161
	* builtins.c (expand_builtin_int_roundingfn): Always fall
	back to floor/ceil and its variants even if they may be
	not available.
	(expand_builtin_cexpi): As a fallback if we
	don't have builtins for sincos or cexp create a function
	declaration for cexp and expand to a call to that.
