Nick Fitzgerald 2af544de8b Update to cranelift 0.58.0 and enable (but ignore) reference types and bulk memory tests (#926)
* Update cranelift to 0.58.0

* Update `wasmprinter` dep to require 0.2.1

We already had it in the lock file, but this ensures we won't ever go back down.

* Ensure that our error messages match `assert_invalid`'s

The bulk of this work was done in
https://github.com/bytecodealliance/wasmparser/pull/186 but now we can test it
at the `wasmtime` level as well.

Fixes #492

* Stop feeling guilty about not matching `assert_malformed` messages

Remove the "TODO" and stop printing warning messages. These would just be busy
work to implement, and getting all the messages the exact same relies on using
the same structure as the spec interpreter's parser, which means that where you
have a helper function and they don't, then things go wrong, and vice versa. Not
worth it.

Fixes #492

* Enable (but ignore) the reference-types proposal tests

* Match test suite directly, instead of roundabout starts/endswith

* Enable (but ignore) bulk memory operations proposal test suite
