Alex Crichton 2127c3a369 Fix CI for main (#4486)
* Skip new `table_ops` test under emulation

When emulating we already have to disable most pooling-allocator related
tests so this commit carries over that logic to the new fuzz test which
may run some configurations with the pooling allocator depending on the
random input.

* Fix panics in s390x codegen related to aliases

This commit fixes an issue introduced as part of the fix for
GHSA-5fhj-g3p3-pq9g. The `reftyped_vregs` list given to `regalloc2` is
not allowed to have duplicates in it and while the list originally
doesn't have duplicates once aliases are applied the list may have
duplicates. The fix here is to perform another pass to remove duplicates
after the aliases have been processed.

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.
