SquirrelFish has been mostly tested under GCC. For GCC, we use computed goto to make a fast interpreter loop, for other compilers we use a loop with a "switch" statement. We need to make sure that SquirrelFish works correctly in this mode on Windows under MSVC, and that it is not a performance regression compared to trunk.
Eventually we may want to do a bit of inline assembly to implement the dispatch.

Oliver tested on Windows. The speedup is not as great as on Mac, but there's still a speedup, so this blocker can be closed.
