Paul Mackerras 2491aa7fc5 core: Make popcnt* take two cycles 
This moves the calculation of the result for popcnt* into the
countbits unit, renamed from countzero, so that we can take two cycles
to get the result.  The motivation for this is that the popcnt*
calculation was showing up as a critical path.
