This patch refactors the current hypercall infrastructure to better support

UD exception that would occur if you used the wrong hypercall instruction
for the underlying architecture and replacing it with the right one lazily.

This doesn't work right for SVM. It keeps looping indefinitely; on a kvm_stat run, I get about 230,000 light vm exits per second, with the hypercall never returning to the guest.

I just tested kvm.git with (the new) hypercall.flat testcase. Seems to work fine.
