4722 (variable_canonicalize): Remove.
4723 (shared_var_p): New inline function.
4724 (unshare_variable): Maintain cur_loc_changed and
4725 in_changed_variables fields. If var was in changed_variables,
4726 replace it there with new_var. Just copy cur_loc instead of
4727 resetting it to something else.

4732 (canonicalize_loc_order_check): Verify that cur_loc is NULL
4733 and in_changed_variables and cur_loc_changed is false.
4734 (variable_merge_over_cur): Clear cur_loc, in_changed_variables

4737 (dataflow_set_preserve_mem_locs): Use shared_var_p. When
4738 removing loc that is equal to cur_loc, clear cur_loc,
4739 set cur_loc_changed and ensure variable_was_changed is called.
4740 (dataflow_set_remove_mem_locs): Use shared_var_p. Only

4742 clear cur_loc and set cur_loc_changed. Don't recompute cur_loc here.

4746 (variable_was_changed): If dv had some var in changed_variables
4747 already, reset in_changed_variables flag for it and propagate
4748 cur_loc_changed over to the new variable. On empty var
4749 always set cur_loc_changed. Set in_changed_variables on whatever
4750 var is added to changed_variables.
4751 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
4752 Use shared_var_p. When removing loc that is equal to cur_loc,
4753 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
4754 end, don't set it to something else, just call variable_was_changed.
4755 (delete_slot_part): Use shared_var_p. When cur_loc equals to
4756 loc being removed, clear cur_loc and set cur_loc_changed.

4759 (vt_expand_loc_callback): Add dummy mode in which no rtxes are
4760 allocated. Always create SUBREGs if simplify_subreg failed.
4761 Prefer to use cur_loc, when that fails and still in

4763 cur_loc_changed of variables which had to change cur_loc and
4764 compute elcd->cur_loc_changed if any of the subexpressions used
4765 had to change cur_loc.
4766 (vt_expand_loc): Adjust to pass arguments in
4767 expand_loc_callback_data structure.
4768 (vt_expand_loc_dummy): New function.
4769 (emitted_notes): New variable.

4771 that weren't used for any other decl in current
4772 emit_notes_for_changes call call vt_expand_loc_dummy to update
4773 cur_loc. For -fno-var-tracking-assignments, set cur_loc to
4774 first loc_chain location if NULL before. Always use just
4775 cur_loc instead of first loc_chain location. When cur_loc_changed
4776 is false, when not --enable-checking=rtl just don't emit any note.
4777 When rtl checking, compute the note and assert it is the same
4778 as previous note. Clear cur_loc_changed and in_changed_variables
4779 at the end before removing from changed_variables.
4780 (check_changed_vars_3): New function.
4781 (emit_notes_for_changes): Traverse changed_vars to call
