Summary: Wasm is chatty (was: V8 correctness failure in configs: x64,fullcode:x64,ignition_staging)
In ignition_staging, we get a bunch of extra console output:
/mnt/scratch0/clusterfuzz/slave-bot/inputs/fuzzer-testcases/fuzz-00086.js:117: Converted asm.js to WebAssembly: success
/mnt/scratch0/clusterfuzz/slave-bot/inputs/fuzzer-testcases/fuzz-00086.js:117: Instantiated asm.js: success

Is there a general suppression option? If not, I'll just suppress everything like this on demand. How many different output lines are there and what would be a good regexp to capture them all?
