Several failures with the attached files

[juanjux]

js_fail.tar.gz

The files attached above produce several problems with the JS Driver:

• Blacklisted types that should have been promoted to semantic objects (FunctionDeclaration, ImportDeclaration, ImportSpecifier, BlockStatement, etc).

• partial parse: message is not defined errors.

• Some failed checks on transforms like check: key "specifiers": field was not used: leadingComments.

They also generate many Unannotated roles but I'll be fixing those as part of #28 and #29.
