with the slight caveat that I think it might be a wee bit better if
UMIP emulation used a separate define UMIP_REPORTED_CR0.
Why, do you see CR0_STATE and UMIP_REPORTED_CR0 becoming different at
some point?
I'm assuming that UMIP_REPORTED_CR0 will never change.  If CR0 gets a
new field that we set some day, then I assume that CR0_STATE would add
that bit but UMIP_REPORTED_CR0 would not.
