    Simplify -ddump-json implementation
    
    This patch takes the much simpler route of whenever the compiler tries
    to output something. We just dump a JSON document there and then.
    
    I think this should be sufficient to work with and anything more refined
    quickly got complicated as it was necessary to demarcate message scopes
    and so on.
