[Compiler-sig] Changes to python.asdl

[Finn Bock]

Hi,

I just committed a few small changes to the python.asdl (something
caused syncmail to blow up so the checkin mail might be missing) and I'm
little worried that such changes cause a lot of pain to your code for
the CPython AST tree. I don't have a toolchain available so that I can
compile and test your C code yet.

I know that we are still in the sandbox and so we should be allowed to
play, I want to play nice.

regards,
finn
