Derek Schuff 92e836cfd2 [WebAssembly] Improve support for WebAssembly binary format
Mostly this change adds support converting to and from
YAML which will allow us to write more test cases for
the WebAssembly MC and lld ports.

Better support for objdump, readelf, and nm will be in
followup CLs.

I had to update the two wasm test binaries because they
used the old style 'name' section which is no longer
supported.
