Apparently, Tom ran into an ICE when we were adding support for new
clauses back in the gomp-4_0-branch days. This patch shouldn't be
necessary because all of the clauses are fully implemented now, but
it may prevent similar bugs from occurring in the future at least
during development.
Is this patch OK for trunk? I bootstrapped and regtested it for x86_64
Linux with nvptx offloading.
Thanks,
Cesar

Lots of other places in the same function use gcc_unreachable (). I think
using gcc_unreachable () here as well would be more appropriate than
special-casing this one place in this function to use "unknown".

How's this? (Obvious, but re-tested anyway.)
Thanks,
