30836 cur_loc_changed over to the new variable. On empty var
30837 always set cur_loc_changed. Set in_changed_variables on whatever
30838 var is added to changed_variables.
30839 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
30840 Use shared_var_p. When removing loc that is equal to cur_loc,

30842 end, don't set it to something else, just call variable_was_changed.
30843 (delete_slot_part): Use shared_var_p. When cur_loc equals to

30851 cur_loc_changed of variables which had to change cur_loc and

30853 had to change cur_loc.

30862 first loc_chain location if NULL before. Always use just
30863 cur_loc instead of first loc_chain location. When cur_loc_changed
30864 is false, when not --enable-checking=rtl just don't emit any note.
30865 When rtl checking, compute the note and assert it is the same
30866 as previous note. Clear cur_loc_changed and in_changed_variables
30867 at the end before removing from changed_variables.
