[Dlang-internal] astTypeName-helper

[Stefan Koch via Dlang-internal]

Hi,

I just wanted to announce a handy tool that I have written to 
better work with dmds ast.
It is a visitor that will give you the dynamic type of a given 
ast-node.
Assuming the PR[0] is merged, beginning dmd-devs will have an 
easier time to figure out which ast-nodes are used to which end 
and will be able to work with dmd more effectively.

Cheers,
Stefan
