strict version of operations on IntMap and IntSet

Hi.

- From a discussion I had some time ago on haskell-cafe, it seems that all
operations on IntMap and IntSet are lazy.

The only exception is `alter`, for IntMap.

This can be a problem.
As an example, using `fromList` (both from IntMap and IntSet) seems to
be rather unfriendly to the garbage collector.


Is it possible to have strict variants of the most common operations?


Thanks  Manlio Perillo
