37152 (unshare_variable): Maintain cur_loc_changed and
37153 in_changed_variables fields. If var was in changed_variables,
37154 replace it there with new_var. Just copy cur_loc instead of
37155 resetting it to something else.

37175 already, reset in_changed_variables flag for it and propagate
37176 cur_loc_changed over to the new variable. On empty var
37177 always set cur_loc_changed. Set in_changed_variables on whatever
37178 var is added to changed_variables.
37179 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
37180 Use shared_var_p. When removing loc that is equal to cur_loc,
37181 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
37182 end, don't set it to something else, just call variable_was_changed.
37183 (delete_slot_part): Use shared_var_p. When cur_loc equals to
37184 loc being removed, clear cur_loc and set cur_loc_changed.

37187 (vt_expand_loc_callback): Add dummy mode in which no rtxes are
37188 allocated. Always create SUBREGs if simplify_subreg failed.

37191 cur_loc_changed of variables which had to change cur_loc and
37192 compute elcd->cur_loc_changed if any of the subexpressions used
37193 had to change cur_loc.

37202 first loc_chain location if NULL before. Always use just
37203 cur_loc instead of first loc_chain location. When cur_loc_changed
37204 is false, when not --enable-checking=rtl just don't emit any note.
37205 When rtl checking, compute the note and assert it is the same
37206 as previous note. Clear cur_loc_changed and in_changed_variables
37207 at the end before removing from changed_variables.
