I'll try building a mips-elf simulator and bootstraping an IRIX 6.5
system to see if I can figure out whats going on.  This is a bit
odd though, my 2002-06-13 cleanups shouldn't have affected any
behaviour (unless the MIPS backend explicitly disables if-conversion,
or cleanup_cfg isn't idempotent, i.e. running it more than once has
an observable effect on MIPS).

Sorry for any inconvenience.
