19424 already, reset in_changed_variables flag for it and propagate
19425 cur_loc_changed over to the new variable. On empty var
19426 always set cur_loc_changed. Set in_changed_variables on whatever
19427 var is added to changed_variables.
19428 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
19429 Use shared_var_p. When removing loc that is equal to cur_loc,
19430 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
19431 end, don't set it to something else, just call variable_was_changed.
19432 (delete_slot_part): Use shared_var_p. When cur_loc equals to

19440 cur_loc_changed of variables which had to change cur_loc and
19441 compute elcd->cur_loc_changed if any of the subexpressions used
19442 had to change cur_loc.
19443 (vt_expand_loc): Adjust to pass arguments in

19450 cur_loc. For -fno-var-tracking-assignments, set cur_loc to
19451 first loc_chain location if NULL before. Always use just
19452 cur_loc instead of first loc_chain location. When cur_loc_changed
19453 is false, when not --enable-checking=rtl just don't emit any note.
19454 When rtl checking, compute the note and assert it is the same
19455 as previous note. Clear cur_loc_changed and in_changed_variables
19456 at the end before removing from changed_variables.
