Brian Kessler 9c7bf0807a math/big: avoid unneeded sticky bit calculations
As noted in the TODO comment, the sticky bit is only used
when the rounding bit is zero or the rounding mode is
ToNearestEven.  This change makes that check explicit and
will eliminate half the sticky bit calculations on average
when rounding mode is not ToNearestEven.
