Remove two uses of IntMap.sizewip/sjakobi/less-intmap-size
IntMap.size is O(n). The new code should be slightly more efficient.
The transformation of GHC.CmmToAsm.CFG.calcFreqs.nodeCount can be
described formally as the transformation:
(\sum_{0}^{n-1} \sum_{0}^{k-1} i_nk) + n
==>
(\sum_{0}^{n-1} 1 + \sum_{0}^{k-1} i_nk)
