14292 already, reset in_changed_variables flag for it and propagate
14293 cur_loc_changed over to the new variable. On empty var
14294 always set cur_loc_changed. Set in_changed_variables on whatever
14295 var is added to changed_variables.
14296 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
14297 Use shared_var_p. When removing loc that is equal to cur_loc,

14299 end, don't set it to something else, just call variable_was_changed.

14308 cur_loc_changed of variables which had to change cur_loc and
14309 compute elcd->cur_loc_changed if any of the subexpressions used
14310 had to change cur_loc.

14319 first loc_chain location if NULL before. Always use just
14320 cur_loc instead of first loc_chain location. When cur_loc_changed
14321 is false, when not --enable-checking=rtl just don't emit any note.
14322 When rtl checking, compute the note and assert it is the same
14323 as previous note. Clear cur_loc_changed and in_changed_variables
14324 at the end before removing from changed_variables.
