37563 already, reset in_changed_variables flag for it and propagate
37564 cur_loc_changed over to the new variable. On empty var
37565 always set cur_loc_changed. Set in_changed_variables on whatever
37566 var is added to changed_variables.
37567 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
37568 Use shared_var_p. When removing loc that is equal to cur_loc,
37569 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
37570 end, don't set it to something else, just call variable_was_changed.
37571 (delete_slot_part): Use shared_var_p. When cur_loc equals to
37572 loc being removed, clear cur_loc and set cur_loc_changed.
37573 Set cur_loc_changed if all locations have been removed.

37575 (vt_expand_loc_callback): Add dummy mode in which no rtxes are

37581 had to change cur_loc.

37590 first loc_chain location if NULL before. Always use just
37591 cur_loc instead of first loc_chain location. When cur_loc_changed
37592 is false, when not --enable-checking=rtl just don't emit any note.

37594 as previous note. Clear cur_loc_changed and in_changed_variables
