This patch set establishes an ABI. It basically sets in stone a bunch
of behaviors that the enclave, the kernel, and the out-of-enclave code
must follow.

There are a bunch of things that the enclave can do to %rsp or %rip, for
instance, that it is capable and/or permitted to do.

The ABI seems entirely undocumented and rather lightly designed, which
seems like something we should fix before this is merged.

Also, for a feature as massive and complicated as this one, it seems
irresponsible to not have a selftest. Is that not feasible for some reason?
