This fixes an important warning when building under GHC 7.6 RC1:

Numeric/Natural/Internal.hs:44:10: Warning:
    No explicit method or default declaration for `popCount'
    In the instance declaration for `Bits Natural'

This is because the Num constraint was removed from the Bits typeclass, so popCount and a couple other methods can no longer have default implementations. That is, unless the DefaultSignatures extension is used; see ticket 7135.

This pull request passes (merged 40e1e97 into 8a01f4c).
