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.
