re PR target/49349 (gfortran.dg/char_result_3.f90 fails with -O3)

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.
