34191 (unshare_variable): Maintain cur_loc_changed and
34192 in_changed_variables fields. If var was in changed_variables,
34193 replace it there with new_var. Just copy cur_loc instead of
34194 resetting it to something else.

34214 already, reset in_changed_variables flag for it and propagate
34215 cur_loc_changed over to the new variable. On empty var
34216 always set cur_loc_changed. Set in_changed_variables on whatever
34217 var is added to changed_variables.
34218 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
34219 Use shared_var_p. When removing loc that is equal to cur_loc,
34220 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
34221 end, don't set it to something else, just call variable_was_changed.
34222 (delete_slot_part): Use shared_var_p. When cur_loc equals to
34223 loc being removed, clear cur_loc and set cur_loc_changed.

34226 (vt_expand_loc_callback): Add dummy mode in which no rtxes are
34227 allocated. Always create SUBREGs if simplify_subreg failed.

34230 cur_loc_changed of variables which had to change cur_loc and
34231 compute elcd->cur_loc_changed if any of the subexpressions used
34232 had to change cur_loc.
34233 (vt_expand_loc): Adjust to pass arguments in

34240 cur_loc. For -fno-var-tracking-assignments, set cur_loc to
34241 first loc_chain location if NULL before. Always use just
34242 cur_loc instead of first loc_chain location. When cur_loc_changed
34243 is false, when not --enable-checking=rtl just don't emit any note.
34244 When rtl checking, compute the note and assert it is the same
34245 as previous note. Clear cur_loc_changed and in_changed_variables
34246 at the end before removing from changed_variables.
