1094 cur_loc_changed of variables which had to change cur_loc and
1095 compute elcd->cur_loc_changed if any of the subexpressions used
1096 had to change cur_loc.

1105 first loc_chain location if NULL before. Always use just
1106 cur_loc instead of first loc_chain location. When cur_loc_changed
1107 is false, when not --enable-checking=rtl just don't emit any note.
1108 When rtl checking, compute the note and assert it is the same
1109 as previous note. Clear cur_loc_changed and in_changed_variables
1110 at the end before removing from changed_variables.
1111 (check_changed_vars_3): New function.
