This reduces the number of floating point save/restore cycles required (since
we don't need to restore immediately following the switch, this always happens
in a known context) and allows the kernel hooks to capture state. This lets us
remove calls like "Current()".

This is the same way that Linux operates. We also split management of
PCIDs out of the page tables themselves for simplicity.
