32581 already, reset in_changed_variables flag for it and propagate
32582 cur_loc_changed over to the new variable. On empty var
32583 always set cur_loc_changed. Set in_changed_variables on whatever
32584 var is added to changed_variables.
32585 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
32586 Use shared_var_p. When removing loc that is equal to cur_loc,
32587 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
32588 end, don't set it to something else, just call variable_was_changed.
32589 (delete_slot_part): Use shared_var_p. When cur_loc equals to

32597 cur_loc_changed of variables which had to change cur_loc and
32598 compute elcd->cur_loc_changed if any of the subexpressions used
32599 had to change cur_loc.

32608 first loc_chain location if NULL before. Always use just
32609 cur_loc instead of first loc_chain location. When cur_loc_changed
32610 is false, when not --enable-checking=rtl just don't emit any note.
32611 When rtl checking, compute the note and assert it is the same
32612 as previous note. Clear cur_loc_changed and in_changed_variables
32613 at the end before removing from changed_variables.
