Less code means less bugs so add a knob to skip the compat stuff.

These all look good to me. I had some minor comment about one patch but
not really a big deal and there were more cleanups on top of it, so I
don't mind if it's merged as is.
Actually I think we have a bit of stack reading fixes for 64s radix now
(not a bug fix as such, but we don't need the hash fault logic in radix),
so if I get around to that I can propose the changes in that series.
As far as I can see, there is a v12
