PR c++/90171 - reorganize usual_deallocation_fn_p

When fixing 90171 it struck me as undesirable to have so many separate
functions that all needed to know about the definition of a usual
deallocation function.  So this patch condenses them into one.  I left
destroying_delete_p because it is used by other files as well.

	* call.c (struct dealloc_info): New.
	(usual_deallocation_fn_p): Take a dealloc_info*.
	(aligned_deallocation_fn_p, sized_deallocation_fn_p): Remove.
	(build_op_delete_call): Adjust.
