* Improve dataToTag# magic
dataToTag# is a bit unsatisfactory because it requires
its argument to be evaluated, and we don't have a good
way to enforce that. This patch adds some comments, and
makes exprOkForSpeculation a bit less picky in the case
of dataToTag# (since the argument may, in fact, not be
eval'd).
