- Add primops for {read,write,index}{Int,Word}{8,16,32,64}OffAddr.
    This enables us to remove all the _casm_s from Int/Word.

  - Replace new{Char,Int,etc.}Array# with newByteArray# (save a few primops,
    at the cost of having to know the size of these types in PrelArr).

  - Implement MArray/IArray support for sized types.  finally.

  - Move the guts of the sized types into ghc/lib/std, we'll need
    them for doing more FFIish things in the Prelude.
