Regardless of the outcome of Jesse's request for an if-ladder, the
substance of the patches look sound.
However, I remain unconvinced that there are 32 fence registers on IVB.
Daniel's evidence is based upon the size of the register map (and not
on the BSPEC explicitly stating a change to 32 ;-), but most tellingly
the bitfields for fence-number in other registers have not been updated -
so we can only safely allocated the first 16 anyway...
(For instance, FBC_CTL).
