21144 already, reset in_changed_variables flag for it and propagate
21145 cur_loc_changed over to the new variable. On empty var
21146 always set cur_loc_changed. Set in_changed_variables on whatever
21147 var is added to changed_variables.
21148 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
21149 Use shared_var_p. When removing loc that is equal to cur_loc,
21150 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
21151 end, don't set it to something else, just call variable_was_changed.
21152 (delete_slot_part): Use shared_var_p. When cur_loc equals to

21160 cur_loc_changed of variables which had to change cur_loc and

21162 had to change cur_loc.

21171 first loc_chain location if NULL before. Always use just
21172 cur_loc instead of first loc_chain location. When cur_loc_changed
21173 is false, when not --enable-checking=rtl just don't emit any note.
21174 When rtl checking, compute the note and assert it is the same
21175 as previous note. Clear cur_loc_changed and in_changed_variables
