Nick Fitzgerald cc8d7778e2 Make the table_ops test case generator use globals as well

This will make it generate `table.set`s that come from `global.get`s and
`global.get`s that come from `table.set`s. Ultimately, it should give us much
more fuzzing coverage of `externref` globals, their barriers, and passing
`externref`s into and out of Wasm to get or set globals.

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.
