31255 (unshare_variable): Maintain cur_loc_changed and
31256 in_changed_variables fields. If var was in changed_variables,
31257 replace it there with new_var. Just copy cur_loc instead of
31258 resetting it to something else.

31278 already, reset in_changed_variables flag for it and propagate
31279 cur_loc_changed over to the new variable. On empty var
31280 always set cur_loc_changed. Set in_changed_variables on whatever
31281 var is added to changed_variables.
31282 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
31283 Use shared_var_p. When removing loc that is equal to cur_loc,
31284 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
31285 end, don't set it to something else, just call variable_was_changed.
31286 (delete_slot_part): Use shared_var_p. When cur_loc equals to
31287 loc being removed, clear cur_loc and set cur_loc_changed.

31294 cur_loc_changed of variables which had to change cur_loc and
31295 compute elcd->cur_loc_changed if any of the subexpressions used
31296 had to change cur_loc.

31305 first loc_chain location if NULL before. Always use just
31306 cur_loc instead of first loc_chain location. When cur_loc_changed
31307 is false, when not --enable-checking=rtl just don't emit any note.
31308 When rtl checking, compute the note and assert it is the same
31309 as previous note. Clear cur_loc_changed and in_changed_variables
31310 at the end before removing from changed_variables.
