Alex Crichton 1f534c5799 Change spectest fuzzing to throw out some fuzz inputs (#5597)
A fuzz bug came in last night from #5567 where spectest fuzzing will
first generate a config, possibly with SSE features for SIMD disabled,
only to have SIMD later enabled by `set_spectest_compliant`. This commit
fixes the issue by changing to `is_spectest_compliant` as a query and
throwing out the fuzz case if it isn't. This means that the spectest
fuzzer will throw out more inputs but means we can continue to generate
interesting configs and such for other inputs.

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.
