36361 had to change cur_loc.

36370 first loc_chain location if NULL before. Always use just
36371 cur_loc instead of first loc_chain location. When cur_loc_changed
36372 is false, when not --enable-checking=rtl just don't emit any note.
36373 When rtl checking, compute the note and assert it is the same
36374 as previous note. Clear cur_loc_changed and in_changed_variables
