29201 had to change cur_loc.

29210 first loc_chain location if NULL before. Always use just
29211 cur_loc instead of first loc_chain location. When cur_loc_changed
29212 is false, when not --enable-checking=rtl just don't emit any note.
29213 When rtl checking, compute the note and assert it is the same
29214 as previous note. Clear cur_loc_changed and in_changed_variables
29215 at the end before removing from changed_variables.
