Alex Crichton fc6328ae06 Temporarily disable SIMD fuzzing on CI (#3376 )

We've got a large crop of fuzz-bugs from fuzzing with enabled-with-SIMD
on oss-fuzz but at this point the fuzz stats from oss-fuzz say that the
fuzzers like v8 are spending less than 50% of its time actually fuzzing
and presumably mostly hitting crashes and such. While we fix the other
issues this disables simd for fuzzing with v8 so we can try to see if we
can weed out other issues.

Fuzzing Infrastructure for Wasmtime

This crate provides test case generators and oracles for use with fuzzing.

These generators and oracles are generally independent of the fuzzing engine that might be using them and driving the whole fuzzing process (e.g. libFuzzer or AFL). As such, this crate does not contain any actual fuzz targets itself. Those are generally just a couple lines of glue code that plug raw input from (for example) libFuzzer into a generator, and then run one or more oracles on the generated test case.

If you're looking for the actual fuzz target definitions we currently have, they live in wasmtime/fuzz/fuzz_targets/* and are driven by cargo fuzz and libFuzzer.
