Account for tail expressions when pointing at return type When there's a type mismatch we make an effort to check if it was caused by a function's return type. This logic now makes sure to only point at the return type if the error happens in a tail expression. Turn `walk_parent_nodes` method into an iterator. CC #39968, CC #40799.
