* Make arrays safer (e.g. trac #1046)
This is a divergence from Haskell 98.
* Add (numElements :: Ix i => a i e -> Int) to IArray class
* Array types get an extra field for numElements, e.g.
{{{
-data UArray i e = UArray !i !i ByteArray#
+data UArray i e = UArray !i !i !Int ByteArray#
}}}
This is a cache of rangeSize(l,u)
* Add safeRangeSize (always returns >= 0)
* Add safeIndex (use unsafeIndex (no Ix inRange check),
but check index < numElements)
* unsafeForeignPtrToStorableArray gained an (Ix i) context
