PR c++/81236 - ICE with template-id in generic lambda

	* semantics.c (finish_id_expression): Remove special dependent case.
	Avoid some later pieces when dependent.
	(finish_qualified_id_expr): Do normal BASELINK handling in a
	template.  Always build a SCOPE_REF for a destructor BIT_NOT_EXPR.
	(parsing_default_capturing_generic_lambda_in_template): Remove.
	* parser.c (cp_parser_postfix_dot_deref_expression): Always give an
	error for types that will never be complete.
	* mangle.c (write_expression): Add sanity check.
	* tree.c (build_qualified_name): Add sanity check.
	(cp_walk_subtrees): Walk into the class context of a BASELINK.
	* lambda.c (add_capture): Improve diagnostic for generic lambda
	capture failure.
	* call.c (build_new_method_call_1): Print the right constructor
	name.
