`-verify-machineinstrs` caught a few issues the last time I tried to merge this so i'd prefer to keep it unless there's a strong reason not to.

This test tries to stack allocate ~5gb which isn't valid on i386 so it wasn't clear to me what the point of the test was. I can add it back if you'd prefer.
