Looking at the article, user mode seems to be optional, so I'm not against it,
but it does look weird. How does ork1sim do it?
It's haphazard. There are checks for supervisor in the l_mtspr and l_mfspr
insns, but not other uses of the sprs, such as l_rfe.
How about we make the optional user mode a feature bit? This way we are
closer to ork1sim, but don't have the problem that testing is hindered.
