re PR middle-end/45567 (__builtin_popcountl ICEs with -ftree-ter) 

	PR middle-end/45567
	* builtins.c (expand_builtin_interclass_mathfn, expand_builtin_cexpi,
	expand_builtin_powi): Remove subtarget argument, pass NULL_RTX instead.
	(expand_builtin): Adjust caller.
	(expand_builtin_unop): Only use subtarget if it has the right mode.

	* gcc.dg/pr45567.c: New test.
