This is the last item of the OpenACC 3.3 spec. It includes the implicit-name version of 'routine', plus significant refactorings to make the two work together. The implicit name version is represented as an attribute on the function call. This patch also implements the clauses for the implicit-name version, as well as the A.3.4 warning.
