Update to the latest spec_testsuite and dependencies. (#803)

* Update to the latest spec_testsuite and dependencies.

Update to target-lexicon 0.10, cranelift 0.54, wast 0.6, faerie 0.14,
and the latest spec_testsuite.

For wast and cranelift-wasm, update the code for API changes.

* Factor out the code for matching f32, f64, and v128.

This takes the idea from #802 to split out `f32_matches`, `f64_matches`,
and `v128_matches` functions, which better factor out the matching
functionality between scalar and vector.
