this afternoon i investigated running unit tests with virtual memory enabled,
with the expectation that they'll come from the I-Cache.

i discovered that I-Cache "priv-mode" is not hooked up in TestIssuer.

then, on trying to fix that, i discovered that the MSR is read one
cycle too late

i will fix that tomorrow, but it is quite intrusive - quite a big change to the
FSM.  it's in the TODO notes of TestIssuer.
