2446 and in_changed_variables and cur_loc_changed is false.

2460 already, reset in_changed_variables flag for it and propagate
2461 cur_loc_changed over to the new variable. On empty var
2462 always set cur_loc_changed. Set in_changed_variables on whatever
2463 var is added to changed_variables.
2464 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
2465 Use shared_var_p. When removing loc that is equal to cur_loc,
2466 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
2467 end, don't set it to something else, just call variable_was_changed.
2468 (delete_slot_part): Use shared_var_p. When cur_loc equals to
2469 loc being removed, clear cur_loc and set cur_loc_changed.

2476 cur_loc_changed of variables which had to change cur_loc and
2477 compute elcd->cur_loc_changed if any of the subexpressions used
2478 had to change cur_loc.

2486 cur_loc. For -fno-var-tracking-assignments, set cur_loc to
2487 first loc_chain location if NULL before. Always use just
2488 cur_loc instead of first loc_chain location. When cur_loc_changed
2489 is false, when not --enable-checking=rtl just don't emit any note.
2490 When rtl checking, compute the note and assert it is the same
2491 as previous note. Clear cur_loc_changed and in_changed_variables
2492 at the end before removing from changed_variables.
2493 (check_changed_vars_3): New function.
2494 (emit_notes_for_changes): Traverse changed_vars to call
