This patchset fixes several bugs in the emulator and in vmx invalid guest
state emulation. They are sufficient to boot several Linux and Windows
guests, so the last patch turns vmx invalid guest state emulation on by
default.
The first patch is a little hacky; we should try to emulate svm here by making
cpl a state, not a cache.
