29643 cur_loc_changed of variables which had to change cur_loc and

29645 had to change cur_loc.

29654 first loc_chain location if NULL before. Always use just
29655 cur_loc instead of first loc_chain location. When cur_loc_changed
29656 is false, when not --enable-checking=rtl just don't emit any note.
29657 When rtl checking, compute the note and assert it is the same
29658 as previous note. Clear cur_loc_changed and in_changed_variables
29659 at the end before removing from changed_variables.
