25831 (unshare_variable): Maintain cur_loc_changed and
25832 in_changed_variables fields. If var was in changed_variables,
25833 replace it there with new_var. Just copy cur_loc instead of
25834 resetting it to something else.

25854 already, reset in_changed_variables flag for it and propagate
25855 cur_loc_changed over to the new variable. On empty var
25856 always set cur_loc_changed. Set in_changed_variables on whatever
25857 var is added to changed_variables.
25858 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
25859 Use shared_var_p. When removing loc that is equal to cur_loc,
25860 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
25861 end, don't set it to something else, just call variable_was_changed.
25862 (delete_slot_part): Use shared_var_p. When cur_loc equals to
25863 loc being removed, clear cur_loc and set cur_loc_changed.

25866 (vt_expand_loc_callback): Add dummy mode in which no rtxes are
25867 allocated. Always create SUBREGs if simplify_subreg failed.

25870 cur_loc_changed of variables which had to change cur_loc and
25871 compute elcd->cur_loc_changed if any of the subexpressions used
25872 had to change cur_loc.

25881 first loc_chain location if NULL before. Always use just
25882 cur_loc instead of first loc_chain location. When cur_loc_changed
25883 is false, when not --enable-checking=rtl just don't emit any note.
25884 When rtl checking, compute the note and assert it is the same
25885 as previous note. Clear cur_loc_changed and in_changed_variables
25886 at the end before removing from changed_variables.
