519 (unshare_variable): Maintain cur_loc_changed and

521 replace it there with new_var. Just copy cur_loc instead of
522 resetting it to something else.
523 (variable_union): Don't recompute cur_loc. Use shared_var_p.

526 of their DEBUG_EXPR_TREE_DECLs.
527 (canonicalize_loc_order_check): Verify that cur_loc is NULL
528 and in_changed_variables and cur_loc_changed is false.

535 (dataflow_set_remove_mem_locs): Use shared_var_p. Only

537 clear cur_loc and set cur_loc_changed. Don't recompute cur_loc here.

540 (dataflow_set_different_1): Adjust variable_different_p caller.
541 (variable_was_changed): If dv had some var in changed_variables
542 already, reset in_changed_variables flag for it and propagate
543 cur_loc_changed over to the new variable. On empty var
544 always set cur_loc_changed. Set in_changed_variables on whatever
545 var is added to changed_variables.
546 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
547 Use shared_var_p. When removing loc that is equal to cur_loc,
548 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
549 end, don't set it to something else, just call variable_was_changed.
550 (delete_slot_part): Use shared_var_p. When cur_loc equals to
551 loc being removed, clear cur_loc and set cur_loc_changed.
552 Set cur_loc_changed if all locations have been removed.
553 (struct expand_loc_callback_data): New type.
554 (vt_expand_loc_callback): Add dummy mode in which no rtxes are
555 allocated. Always create SUBREGs if simplify_subreg failed.
556 Prefer to use cur_loc, when that fails and still in
557 changed_variables (and seen first time) recompute it. Set
558 cur_loc_changed of variables which had to change cur_loc and
559 compute elcd->cur_loc_changed if any of the subexpressions used
560 had to change cur_loc.
561 (vt_expand_loc): Adjust to pass arguments in

563 (vt_expand_loc_dummy): New function.
564 (emitted_notes): New variable.

566 that weren't used for any other decl in current
567 emit_notes_for_changes call call vt_expand_loc_dummy to update
568 cur_loc. For -fno-var-tracking-assignments, set cur_loc to
569 first loc_chain location if NULL before. Always use just
570 cur_loc instead of first loc_chain location. When cur_loc_changed
571 is false, when not --enable-checking=rtl just don't emit any note.
572 When rtl checking, compute the note and assert it is the same
573 as previous note. Clear cur_loc_changed and in_changed_variables
574 at the end before removing from changed_variables.
575 (check_changed_vars_3): New function.
576 (emit_notes_for_changes): Traverse changed_vars to call
