	PR middle-end/36282

	TREE_SYMBOL_REFERENCED (DECL_ASSEMBLER_NAME (decl)) if
	DECL_ASSEMBLER_NAME_SET_P (decl).
	(maybe_apply_pending_pragma_weaks): Exit early if
	vec_safe_is_empty (pending_weaks) rather than only when
	!pending_weaks.

	set assembler name back to NULL afterwards.

	* c-c++-common/pr36282-2.c: New test.
