Fixes the incorrect documentation in Data.HashMap.Lazy.fromList / Data.HashMap.Internal.fromList: This takes linearithmic time rather than linear time, since we do n insertions, each of which takes (assuming no collisions!) log32(n) steps as per the documentation of insert.

Fixes #309

How come fromList is O(n) instead of O(n*log n)?
