6135 already, reset in_changed_variables flag for it and propagate
6136 cur_loc_changed over to the new variable. On empty var
6137 always set cur_loc_changed. Set in_changed_variables on whatever
6138 var is added to changed_variables.
6139 (set_slot_part): Clear cur_loc_changed and in_changed_variables.

6163 cur_loc instead of first loc_chain location. When cur_loc_changed
6164 is false, when not --enable-checking=rtl just don't emit any note.
