Then, we can build something with MSVC, dump it to .s format, and paste individual records into a test and mix and match them as necessary to create all the interesting cases.

All we care about is that the AST is reconstructed correctly.  I'll add this to my todo list because I think it would be a really useful feature.

That sounds like a really useful feature.
