Internal compiler classes always return a string (#918)

* Internal compiler classes always return a string (the internal has_code flag has been removed for simplicity)
* Add :string method signature to compile method everywhere.

-- compiler->has_code seems silly. Why not have proper return values?
 - what is 'user literal support', why are unit tests skipped?
