6635 var is added to changed_variables.
6636 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
6637 Use shared_var_p. When removing loc that is equal to cur_loc,

6640 (delete_slot_part): Use shared_var_p. When cur_loc equals to

6648 cur_loc_changed of variables which had to change cur_loc and
6649 compute elcd->cur_loc_changed if any of the subexpressions used
6650 had to change cur_loc.
6651 (vt_expand_loc): Adjust to pass arguments in

6659 first loc_chain location if NULL before. Always use just
6660 cur_loc instead of first loc_chain location. When cur_loc_changed
6661 is false, when not --enable-checking=rtl just don't emit any note.
6662 When rtl checking, compute the note and assert it is the same
6663 as previous note. Clear cur_loc_changed and in_changed_variables
6664 at the end before removing from changed_variables.
6665 (check_changed_vars_3): New function.
