34181 (unshare_variable): Maintain cur_loc_changed and
34182 in_changed_variables fields. If var was in changed_variables,
34183 replace it there with new_var. Just copy cur_loc instead of

34204 already, reset in_changed_variables flag for it and propagate
34205 cur_loc_changed over to the new variable. On empty var
34206 always set cur_loc_changed. Set in_changed_variables on whatever
34207 var is added to changed_variables.
34208 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
34209 Use shared_var_p. When removing loc that is equal to cur_loc,
34210 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
34211 end, don't set it to something else, just call variable_was_changed.
34212 (delete_slot_part): Use shared_var_p. When cur_loc equals to
34213 loc being removed, clear cur_loc and set cur_loc_changed.

34216 (vt_expand_loc_callback): Add dummy mode in which no rtxes are

34220 cur_loc_changed of variables which had to change cur_loc and
34221 compute elcd->cur_loc_changed if any of the subexpressions used
34222 had to change cur_loc.

34231 first loc_chain location if NULL before. Always use just
34232 cur_loc instead of first loc_chain location. When cur_loc_changed
34233 is false, when not --enable-checking=rtl just don't emit any note.
34234 When rtl checking, compute the note and assert it is the same
34235 as previous note. Clear cur_loc_changed and in_changed_variables
34236 at the end before removing from changed_variables.
