Log:
	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.
