9337 cur_loc instead of first loc_chain location. When cur_loc_changed
9338 is false, when not --enable-checking=rtl just don't emit any note.
9339 When rtl checking, compute the note and assert it is the same
9340 as previous note. Clear cur_loc_changed and in_changed_variables
9341 at the end before removing from changed_variables.
