Comment(by simonpj):
Johan, can you drive this ticket to conclusion?
Is the Right Thing to implement a `word2Double#` primitive? And
`word2Float#` I guess. What exactly does it do? Just treat the word as a
unsigned integer, thus behaving just like `int2Double#` (at least as I
understand it)?
If so why not do precisely that, rather than use workarounds? Presuambly
the code generators would need to be educated.
Simon
