Hi!
While most of the sanitization is done in the FEs (c-family/),
some is done in the middle-end (ubsan pass) or when folding
__builtin_unreachable ().
This patch fixes ICE with that, bootstrapped/regtested on x86_64-linux and
i686-linux, committed to trunk as obvious.

* ubsan.c (ubsan_instrument_unreachable): Call
