Generate Debug Symbols

[bettinaheim]

We need to figure out how to provide proper debug support. In particular, we need to look into generating debug symbols. Right now, the debug support in VS works via relying onto the debug support for the generated C# code. This becomes less and less reliable as we do more complex rewrites (like e.g. generating unique symbol names as we inline code blocks).

The time line for this may be fairly long, as it is a larger piece and currently not staffed. Hence the help wanted. :)
