21173 already, reset in_changed_variables flag for it and propagate
21174 cur_loc_changed over to the new variable. On empty var
21175 always set cur_loc_changed. Set in_changed_variables on whatever
21176 var is added to changed_variables.
21177 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
21178 Use shared_var_p. When removing loc that is equal to cur_loc,
21179 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
21180 end, don't set it to something else, just call variable_was_changed.
21181 (delete_slot_part): Use shared_var_p. When cur_loc equals to

21189 cur_loc_changed of variables which had to change cur_loc and

21191 had to change cur_loc.

21200 first loc_chain location if NULL before. Always use just
21201 cur_loc instead of first loc_chain location. When cur_loc_changed
21202 is false, when not --enable-checking=rtl just don't emit any note.
21203 When rtl checking, compute the note and assert it is the same
21204 as previous note. Clear cur_loc_changed and in_changed_variables
21205 at the end before removing from changed_variables.
