29986 already, reset in_changed_variables flag for it and propagate
29987 cur_loc_changed over to the new variable. On empty var
29988 always set cur_loc_changed. Set in_changed_variables on whatever
29989 var is added to changed_variables.
29990 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
29991 Use shared_var_p. When removing loc that is equal to cur_loc,

29993 end, don't set it to something else, just call variable_was_changed.
29994 (delete_slot_part): Use shared_var_p. When cur_loc equals to

29998 (vt_expand_loc_callback): Add dummy mode in which no rtxes are
29999 allocated. Always create SUBREGs if simplify_subreg failed.

30002 cur_loc_changed of variables which had to change cur_loc and
30003 compute elcd->cur_loc_changed if any of the subexpressions used
30004 had to change cur_loc.
30005 (vt_expand_loc): Adjust to pass arguments in

30012 cur_loc. For -fno-var-tracking-assignments, set cur_loc to
30013 first loc_chain location if NULL before. Always use just
30014 cur_loc instead of first loc_chain location. When cur_loc_changed
30015 is false, when not --enable-checking=rtl just don't emit any note.
30016 When rtl checking, compute the note and assert it is the same
30017 as previous note. Clear cur_loc_changed and in_changed_variables
30018 at the end before removing from changed_variables.
