Clemens Backes a5192ac12f [wasm][fuzzer] Print information about exceptions 
We sometimes get non-reproducible exception mismatches in the fuzzers.
This might come from OOM exceptions.
This CL makes us print some information about them, so we learn more
from the occasional fuzzer reports. In a follow-up we can then handle
OOM exceptions better, if that turns out to cause this.
