Change the 'walk' APIs to use virtual function dispatch

instead .

Change the 'walk' APIs to use virtual dispatch instead of
blocks. This makes it much easier to thread information
through the API, as well to extend the API to handle
recursive visiting of other structures (e.g., Decls
and Patterns).

actually, the ASTStage should be on Translation unit. There can be multiple modules in a context and they can all be in different phases of translation.

statement walk callback functions, where we can stash additional

At present, the only information in the context is the parent

This will be required until there's some sort of error marking
