 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.
