1949eb90af Concurrent concatMap, foldr/build fusion, benchmarks 
* Implement a stream flavor specific (concurrent/wSerial etc.) concatMap
  (concatMapBy). Now concatMap has the same capabilities that the monad bind of
  different streams has. In fact the monad bind is implemented using concatMap

* Use foldr/build fusion for concatMap (currently disabled) and for map/fmap
  and mapM (enabled)

* Add benchmarks for bind/concatMap performance

55f9cfa371 fix foldxM strictness 
The main change is a single line change in StreamK.hs in foldxM routine.

Major changes in this commit are due to:
1) Added strictness tests for all foldl and scanl rotuines
2) refactoring to enable independent benchmarking for StreamK, to measure the
  impact of the change.
