We have wrappers to do for example gpr read/write accesses with,

There's nothing that says we have to have the guest vcpu loaded
when using these wrappers though, so let's introduce a flag that
tells us whether we're inside a vcpu_load context.
On x86 we always access registers within vcpu_load() context. That
simplifies things. Does this not apply here?
Even so, sometimes guest registers are present on the cpu, and sometimes
in shadow variables (for example, msrs might be loaded or not). The
approach here is to always unload and access the variable data. See for
example vmx_set_msr() calling vmx_load_host_state() before accessing msrs.
Seems like this could reduce the if () tree?
