I've committed this patch to trunk to fix a cut-and-paste error in the 
Nios II backend that we've known about for a while, but we lost track of 
getting it fixed.   Now mainline nios2 builds have started to fail 
because recent changes to rtl innards have added some extra 
error-checking that was not there before; previously the failure mode 
was to quietly generate long conditional branches everywhere instead of 
an ICE.
