32135 already, reset in_changed_variables flag for it and propagate
32136 cur_loc_changed over to the new variable. On empty var
32137 always set cur_loc_changed. Set in_changed_variables on whatever
32138 var is added to changed_variables.
32139 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
32140 Use shared_var_p. When removing loc that is equal to cur_loc,
32141 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
32142 end, don't set it to something else, just call variable_was_changed.
32143 (delete_slot_part): Use shared_var_p. When cur_loc equals to

32151 cur_loc_changed of variables which had to change cur_loc and
32152 compute elcd->cur_loc_changed if any of the subexpressions used
32153 had to change cur_loc.

32162 first loc_chain location if NULL before. Always use just
32163 cur_loc instead of first loc_chain location. When cur_loc_changed
32164 is false, when not --enable-checking=rtl just don't emit any note.
32165 When rtl checking, compute the note and assert it is the same
32166 as previous note. Clear cur_loc_changed and in_changed_variables
32167 at the end before removing from changed_variables.
