support for generating annotations from TH
This patch adds support for template haskell generation of annotations. This is currently only possible directly via {-\# ANN function "whatever annotation \#-}.
The attached patch makes it possible to do the same from TH.
Module and type annotations are supported too.
This is part of a larger effort to make it possible to cross-module communicate between template haskell runs. See #7867 (closed) for a longer discussion.
