Fixed in 70d00af8294e.  Actually I just disabled the special path for
'pow(x,y,z)' for the case of huge 'y', which was buggy because it assumed that
SHIFT was a multiple of 5.  I'm ready to reintroduce it if really needed, but it
should be at most a constant factor's difference, not a better algorithmic factor.
