This is an initial prototype of how we can run debugger integration tests on
Windows. cdb and windbg share a command language and debugger engine. Visual
Studio has its own, but we should at least be able to use cdb as the basis for
optimized debug info integration tests.

There's a lot of work to do here still. For example:

- Make fewer assumptions about the SDK location
- Don't assume x64 (important, I need x86 testing)
- More environment isolation, have lit setup vcvars instead of passing LIB and INCLUDE down.
- Write a .py file to replace the grep+sed RUN line

But, this seemed like a good enough concept to commit as is, since it's useful
to me already.
