27525 already, reset in_changed_variables flag for it and propagate
27526 cur_loc_changed over to the new variable. On empty var
27527 always set cur_loc_changed. Set in_changed_variables on whatever
27528 var is added to changed_variables.
27529 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
27530 Use shared_var_p. When removing loc that is equal to cur_loc,
27531 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
27532 end, don't set it to something else, just call variable_was_changed.
27533 (delete_slot_part): Use shared_var_p. When cur_loc equals to

27541 cur_loc_changed of variables which had to change cur_loc and
27542 compute elcd->cur_loc_changed if any of the subexpressions used
27543 had to change cur_loc.

27552 first loc_chain location if NULL before. Always use just
27553 cur_loc instead of first loc_chain location. When cur_loc_changed
27554 is false, when not --enable-checking=rtl just don't emit any note.
27555 When rtl checking, compute the note and assert it is the same
27556 as previous note. Clear cur_loc_changed and in_changed_variables
27557 at the end before removing from changed_variables.
