Subject: [PATCH] ffi 2.0: xfail parser test for `Foo :: #jni_class(...) { ...
 }`

Today's parser doesn't recognize #jni_class as a hash directive
after `::`, so it falls through to expression parsing and errors
at the `#` token. Step 2.1 extends parseConstBinding to accept
the directive (opaque on empty body) and re-snapshots this file
to green.
