PR target/49349
* sel-sched.c (find_place_for_bookkeeping): Add new parameter
(fence_to_rewind). Use it to notice when bookkeeping will be placed
above a fence. Update comments.
(generate_bookkeeping_insn): Rewind fence when bookkeeping code is
placed just above it. Do not allow NULL place_to_insert.
