34611 (unshare_variable): Maintain cur_loc_changed and
34612 in_changed_variables fields. If var was in changed_variables,
34613 replace it there with new_var. Just copy cur_loc instead of

34634 already, reset in_changed_variables flag for it and propagate
34635 cur_loc_changed over to the new variable. On empty var
34636 always set cur_loc_changed. Set in_changed_variables on whatever
34637 var is added to changed_variables.
34638 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
34639 Use shared_var_p. When removing loc that is equal to cur_loc,
34640 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
34641 end, don't set it to something else, just call variable_was_changed.
34642 (delete_slot_part): Use shared_var_p. When cur_loc equals to
34643 loc being removed, clear cur_loc and set cur_loc_changed.

34646 (vt_expand_loc_callback): Add dummy mode in which no rtxes are

34650 cur_loc_changed of variables which had to change cur_loc and
34651 compute elcd->cur_loc_changed if any of the subexpressions used
34652 had to change cur_loc.

34660 cur_loc. For -fno-var-tracking-assignments, set cur_loc to
34661 first loc_chain location if NULL before. Always use just
34662 cur_loc instead of first loc_chain location. When cur_loc_changed
34663 is false, when not --enable-checking=rtl just don't emit any note.
34664 When rtl checking, compute the note and assert it is the same
34665 as previous note. Clear cur_loc_changed and in_changed_variables
34666 at the end before removing from changed_variables.
