re PR c++/32241 (ICE trying to call x.~X(); in a template)

	PR c++/32241
	* pt.c (tsubst_copy_and_build) <case COMPONENT_REF>: If object_type
	is not scalar type, let finish_class_member_access_expr handle
	diagnostics.  Pass BIT_NOT_EXPR argument to
	finish_pseudo_destructor_expr.  Handle SCOPE_REF properly.

	* g++.dg/template/pseudodtor3.C: New test.
