35409 (unshare_variable): Maintain cur_loc_changed and
35410 in_changed_variables fields. If var was in changed_variables,
35411 replace it there with new_var. Just copy cur_loc instead of
35412 resetting it to something else.

35432 already, reset in_changed_variables flag for it and propagate
35433 cur_loc_changed over to the new variable. On empty var
35434 always set cur_loc_changed. Set in_changed_variables on whatever
35435 var is added to changed_variables.
35436 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
35437 Use shared_var_p. When removing loc that is equal to cur_loc,
35438 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
35439 end, don't set it to something else, just call variable_was_changed.
35440 (delete_slot_part): Use shared_var_p. When cur_loc equals to
35441 loc being removed, clear cur_loc and set cur_loc_changed.

35444 (vt_expand_loc_callback): Add dummy mode in which no rtxes are

35448 cur_loc_changed of variables which had to change cur_loc and
35449 compute elcd->cur_loc_changed if any of the subexpressions used
35450 had to change cur_loc.

35459 first loc_chain location if NULL before. Always use just
35460 cur_loc instead of first loc_chain location. When cur_loc_changed
35461 is false, when not --enable-checking=rtl just don't emit any note.
35462 When rtl checking, compute the note and assert it is the same
35463 as previous note. Clear cur_loc_changed and in_changed_variables
35464 at the end before removing from changed_variables.
