Tim: Updated after a whole lot of more testing, testing all codepaths through the emit prologue/epilogue as far as I can see (tested both with and without a frame pointer), testing unwinding for C++ exceptions through a win64cc function, etc. Hopefully this instills a bit more confidence this time. I've included a few open questions about how to rename variables in the patch message and inline that I hope you can give your opinion on.
