Title: Make it buildable with ghc-7.6

Maybe it will be helpful to fix that error message when I get when trying to build data-memocombinators with ghc-7.6.1:

```
Data/MemoCombinators.hs:119:10:
Could not deduce (Num a) arising from a use of `IntTrie.apply'
from the context (Ord a, Bits a)
bound by the type signature for bits :: (Ord a, Bits a) => Memo a
at Data/MemoCombinators.hs:118:9-33
Possible fix:
add (Num a) to the context of
the type signature for bits :: (a -> r) -> a -> r
or the type signature for bits :: (Ord a, Bits a) => Memo a
In the expression: IntTrie.apply (fmap f IntTrie.identity)
In an equation for `bits':
bits f = IntTrie.apply (fmap f IntTrie.identity)
cabal: Error: some packages failed to install:
data-memocombinators-0.4.3 failed during the building phase. The exception
was:
ExitFailure 1
