29615 already, reset in_changed_variables flag for it and propagate
29616 cur_loc_changed over to the new variable. On empty var
29617 always set cur_loc_changed. Set in_changed_variables on whatever
29618 var is added to changed_variables.
29619 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
29620 Use shared_var_p. When removing loc that is equal to cur_loc,
29621 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
29622 end, don't set it to something else, just call variable_was_changed.
29623 (delete_slot_part): Use shared_var_p. When cur_loc equals to

29627 (vt_expand_loc_callback): Add dummy mode in which no rtxes are
29628 allocated. Always create SUBREGs if simplify_subreg failed.
29629 Prefer to use cur_loc, when that fails and still in

29631 cur_loc_changed of variables which had to change cur_loc and
29632 compute elcd->cur_loc_changed if any of the subexpressions used
29633 had to change cur_loc.
29634 (vt_expand_loc): Adjust to pass arguments in

29642 first loc_chain location if NULL before. Always use just
29643 cur_loc instead of first loc_chain location. When cur_loc_changed
29644 is false, when not --enable-checking=rtl just don't emit any note.
29645 When rtl checking, compute the note and assert it is the same
29646 as previous note. Clear cur_loc_changed and in_changed_variables
29647 at the end before removing from changed_variables.
