Add mode to wasm validator to check for web-environment constraints (#584)

In the web embedding, modules are not allowed to import or export
functions which have i64 params or return values. Add a mode to the
validator to check for this, and add flags to s2wasm and wasm-as to
enable or disable this check. Also add tests.
