Alex Crichton 1047c4e156 Fix fuzzers requesting 4gb memories (#3029 )

Wasmtime was updated to reject creation of memories exactly 4gb in size
in #3013, but the fuzzers still had the assumption that any request to
create a host object for a particular wasm type would succeed.
Unfortunately now, though, a request to create a 4gb memory fails. This
is an expected failure, though, so the fix here was to catch the error
and allow it.

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.
