32122 (unshare_variable): Maintain cur_loc_changed and
32123 in_changed_variables fields. If var was in changed_variables,
32124 replace it there with new_var. Just copy cur_loc instead of
32125 resetting it to something else.

32145 already, reset in_changed_variables flag for it and propagate
32146 cur_loc_changed over to the new variable. On empty var
32147 always set cur_loc_changed. Set in_changed_variables on whatever
32148 var is added to changed_variables.
32149 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
32150 Use shared_var_p. When removing loc that is equal to cur_loc,
32151 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
32152 end, don't set it to something else, just call variable_was_changed.
32153 (delete_slot_part): Use shared_var_p. When cur_loc equals to
32154 loc being removed, clear cur_loc and set cur_loc_changed.

32157 (vt_expand_loc_callback): Add dummy mode in which no rtxes are
32158 allocated. Always create SUBREGs if simplify_subreg failed.

32161 cur_loc_changed of variables which had to change cur_loc and
32162 compute elcd->cur_loc_changed if any of the subexpressions used
32163 had to change cur_loc.

32172 first loc_chain location if NULL before. Always use just
32173 cur_loc instead of first loc_chain location. When cur_loc_changed
32174 is false, when not --enable-checking=rtl just don't emit any note.
32175 When rtl checking, compute the note and assert it is the same
32176 as previous note. Clear cur_loc_changed and in_changed_variables
32177 at the end before removing from changed_variables.
