This allows using nontrapping float to int, which makes e.g. fasta 10% faster or so.

The test here may not pass depending on what node version we have on the bots - if it fails I'll remove it.

This now just removes the feature section code, so that we can just rely on the features section.

Rewritten to be feature section friendly, and now it expects to get the list of features as metadata['features'] from finalize. It then passes those to the various invocations we do of binaryen tools.

Also updates binaryen to version_77, and adds a TODO test (which passes on v8 master, but not node lts yet).

Also updates binaryen to version_77 for the binaryen side of things, and adds a TODO test (which passes on v8 master, but not node LTS yet).
