Not that there's anything that could have been done differently in this PR, but it would be nice if GHC provided a ordW32# so that

charToWord32 (C# c#) = W32# (wordToWord32# (int2Word# (ord# c#)))

could become

charToWord32 (C# c#) = W32# (ordW32# c#)

so that during codegen, GHC wouldn't have to try to get rid of the "mask out the upper bits" operation that wordToWord32# normally needs to perform.
