5737 var is added to changed_variables.
5738 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
5739 Use shared_var_p. When removing loc that is equal to cur_loc,

5750 cur_loc_changed of variables which had to change cur_loc and
5751 compute elcd->cur_loc_changed if any of the subexpressions used
5752 had to change cur_loc.
5753 (vt_expand_loc): Adjust to pass arguments in

5761 first loc_chain location if NULL before. Always use just
5762 cur_loc instead of first loc_chain location. When cur_loc_changed
5763 is false, when not --enable-checking=rtl just don't emit any note.
5764 When rtl checking, compute the note and assert it is the same
5765 as previous note. Clear cur_loc_changed and in_changed_variables
5766 at the end before removing from changed_variables.
5767 (check_changed_vars_3): New function.
