This looks good, but I'd be slightly happier if you didn't need that
dyn_cast<GlobalVariable> — we really don't ever want this to fail,
because when it fails, we might not be getting the alignment right.
Fortunately, it looks like the entries are always GlobalVariables.
Please change ConstantStringMap's type to encode this
assumption, and then you shouldn't need the dyn_cast.
With that, this is ready to go in, thanks!
