A blast from the past.  I hate when we end up effectively doing the same 
analysis & bugfix over and over.  I'm OK with this patch for the 
mainline sources.  I'd also approve a patch which changed the remaining 
next_active_insn with next_real_insn within reorg.c and resource.c after 
mainline branches.
