Partial contexts are those where the full context is split between the parts in
the struct and the parts still loaded in hardware. These speed up all of our
syscalls and will be important when we support VM contexts natively.
I'm mostly curious if the rules in 6d43581fdfc4 ("Support partial contexts")
will work for VMs on x86. If not, let me know. =)
