Log Message:
nvmm-x86-vmx: improve the handling of CR0
- Flush the guest TLB when certain CR0 bits change.
- If the guest updates a static bit in CR0, then reflect the change in
VMCS_CR0_SHADOW, for the guest to get the illusion that the change was
applied. The "real" CR0 static bits remain unchanged.
- In vmx_vcpu_{g,s}et_state(), take VMCS_CR0_SHADOW into account.
- Slightly modify the CR4 handling code, just for more symmetry with CR0.
