10165 already, reset in_changed_variables flag for it and propagate
10166 cur_loc_changed over to the new variable. On empty var
10167 always set cur_loc_changed. Set in_changed_variables on whatever
10168 var is added to changed_variables.
10169 (set_slot_part): Clear cur_loc_changed and in_changed_variables.
10170 Use shared_var_p. When removing loc that is equal to cur_loc,

10172 end, don't set it to something else, just call variable_was_changed.
10173 (delete_slot_part): Use shared_var_p. When cur_loc equals to

10178 allocated. Always create SUBREGs if simplify_subreg failed.
10179 Prefer to use cur_loc, when that fails and still in

10181 cur_loc_changed of variables which had to change cur_loc and
10182 compute elcd->cur_loc_changed if any of the subexpressions used
10183 had to change cur_loc.
10184 (vt_expand_loc): Adjust to pass arguments in

10192 first loc_chain location if NULL before. Always use just
10193 cur_loc instead of first loc_chain location. When cur_loc_changed
10194 is false, when not --enable-checking=rtl just don't emit any note.
10195 When rtl checking, compute the note and assert it is the same
10196 as previous note. Clear cur_loc_changed and in_changed_variables
10197 at the end before removing from changed_variables.
