37574 (unshare_variable): Maintain cur_loc_changed and
37575 in_changed_variables fields. If var was in changed_variables,
37576 replace it there with new_var. Just copy cur_loc instead of

37597 already, reset in_changed_variables flag for it and propagate
37598 cur_loc_changed over to the new variable. On empty var
37599 always set cur_loc_changed. Set in_changed_variables on whatever
37600 var is added to changed_variables.
37601 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
37602 Use shared_var_p. When removing loc that is equal to cur_loc,
37603 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
37604 end, don't set it to something else, just call variable_was_changed.
37605 (delete_slot_part): Use shared_var_p. When cur_loc equals to
37606 loc being removed, clear cur_loc and set cur_loc_changed.

37609 (vt_expand_loc_callback): Add dummy mode in which no rtxes are

37613 cur_loc_changed of variables which had to change cur_loc and
37614 compute elcd->cur_loc_changed if any of the subexpressions used
37615 had to change cur_loc.

37624 first loc_chain location if NULL before. Always use just
37625 cur_loc instead of first loc_chain location. When cur_loc_changed
37626 is false, when not --enable-checking=rtl just don't emit any note.
37627 When rtl checking, compute the note and assert it is the same
37628 as previous note. Clear cur_loc_changed and in_changed_variables
37629 at the end before removing from changed_variables.
