29958 (unshare_variable): Maintain cur_loc_changed and
29959 in_changed_variables fields. If var was in changed_variables,
29960 replace it there with new_var. Just copy cur_loc instead of

29981 already, reset in_changed_variables flag for it and propagate
29982 cur_loc_changed over to the new variable. On empty var
29983 always set cur_loc_changed. Set in_changed_variables on whatever
29984 var is added to changed_variables.
29985 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
29986 Use shared_var_p. When removing loc that is equal to cur_loc,
29987 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
29988 end, don't set it to something else, just call variable_was_changed.
29989 (delete_slot_part): Use shared_var_p. When cur_loc equals to

29993 (vt_expand_loc_callback): Add dummy mode in which no rtxes are

29997 cur_loc_changed of variables which had to change cur_loc and
29998 compute elcd->cur_loc_changed if any of the subexpressions used
29999 had to change cur_loc.

30008 first loc_chain location if NULL before. Always use just
30009 cur_loc instead of first loc_chain location. When cur_loc_changed
30010 is false, when not --enable-checking=rtl just don't emit any note.
30011 When rtl checking, compute the note and assert it is the same
30012 as previous note. Clear cur_loc_changed and in_changed_variables
30013 at the end before removing from changed_variables.
