37565 (unshare_variable): Maintain cur_loc_changed and
37566 in_changed_variables fields. If var was in changed_variables,
37567 replace it there with new_var. Just copy cur_loc instead of
37568 resetting it to something else.

37588 already, reset in_changed_variables flag for it and propagate
37589 cur_loc_changed over to the new variable. On empty var
37590 always set cur_loc_changed. Set in_changed_variables on whatever
37591 var is added to changed_variables.
37592 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
37593 Use shared_var_p. When removing loc that is equal to cur_loc,
37594 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
37595 end, don't set it to something else, just call variable_was_changed.
37596 (delete_slot_part): Use shared_var_p. When cur_loc equals to

37604 cur_loc_changed of variables which had to change cur_loc and
37605 compute elcd->cur_loc_changed if any of the subexpressions used
37606 had to change cur_loc.
37607 (vt_expand_loc): Adjust to pass arguments in

37615 first loc_chain location if NULL before. Always use just
37616 cur_loc instead of first loc_chain location. When cur_loc_changed
37617 is false, when not --enable-checking=rtl just don't emit any note.
37618 When rtl checking, compute the note and assert it is the same
37619 as previous note. Clear cur_loc_changed and in_changed_variables
37620 at the end before removing from changed_variables.
