    SVM: introduce a VM entry helper
    
    Neither the register values copying nor the trace entry generation need
    doing in assembly. The VMLOAD invocation can also be further deferred
    (and centralized). Therefore replace the svm_asid_handle_vmrun()
    invocation with one of the new helper.
    
    Similarly move the VM exit side register value copying into
    svm_vmexit_handler().
    
    Now that we always make it out to guest context after VMLOAD,
    svm_sync_vmcb() no longer overrides vmcb_needs_vmsave, making
    svm_vmexit_handler() setting the field early unnecessary.

    SVM: re-work VMCB sync-ing
    
    While the main problem to be addressed here is the issue of what so far
    was named "vmcb_in_sync" starting out with the wrong value (should have
    been true instead of false, to prevent performing a VMSAVE without ever
    having VMLOADed the vCPU's state), go a step further and make the
    sync-ed state a tristate: CPU and memory may be in sync or an update
    may be required in either direction. Rename the field and introduce an
    enum. Callers of svm_sync_vmcb() now indicate the intended new state
    (with a slight "anomaly" when requesting VMLOAD: we could store
    vmcb_needs_vmsave in those cases as the callers request, but the VMCB
    really is in sync at that point, and hence there's no need to VMSAVE in
    case we don't make it out to guest context), and all syncing goes
    through that function.
    
    With that, there's no need to VMLOAD the state perhaps multiple times;
    all that's needed is loading it once before VM entry.
