patch proposal
Actually, it doesn't look all that hard to fix. The attached patch is a little horrible in that it doesn't use the normal method of insert_insn_on_edge(), commit_edge_insertions(), but we are too late for that. I tried, and found verify_flow_info() in commit_edge_insertions() was bombing on stuff already present. Patch currently bootstrapping with BOOT_CFLAGS="-g -O2 -mno-sched-prolog".
