6650 cur_loc instead of first loc_chain location. When cur_loc_changed
6651 is false, when not --enable-checking=rtl just don't emit any note.
6652 When rtl checking, compute the note and assert it is the same
6653 as previous note. Clear cur_loc_changed and in_changed_variables
6654 at the end before removing from changed_variables.
