30818 (unshare_variable): Maintain cur_loc_changed and
30819 in_changed_variables fields. If var was in changed_variables,
30820 replace it there with new_var. Just copy cur_loc instead of
30821 resetting it to something else.

30841 already, reset in_changed_variables flag for it and propagate
30842 cur_loc_changed over to the new variable. On empty var
30843 always set cur_loc_changed. Set in_changed_variables on whatever
30844 var is added to changed_variables.
30845 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
30846 Use shared_var_p. When removing loc that is equal to cur_loc,
30847 clear cur_loc and set cur_loc_changed. If cur_loc is NULL at the
30848 end, don't set it to something else, just call variable_was_changed.
30849 (delete_slot_part): Use shared_var_p. When cur_loc equals to
30850 loc being removed, clear cur_loc and set cur_loc_changed.

30853 (vt_expand_loc_callback): Add dummy mode in which no rtxes are

30857 cur_loc_changed of variables which had to change cur_loc and
30858 compute elcd->cur_loc_changed if any of the subexpressions used
30859 had to change cur_loc.

30868 first loc_chain location if NULL before. Always use just
30869 cur_loc instead of first loc_chain location. When cur_loc_changed
30870 is false, when not --enable-checking=rtl just don't emit any note.
30871 When rtl checking, compute the note and assert it is the same
30872 as previous note. Clear cur_loc_changed and in_changed_variables
30873 at the end before removing from changed_variables.
