llvm: get rid of static_casts from iterators

In commit b7a6aec4eeb4 (convert iterators using static_cast), I switched
all implicit casts to static_cast. It turned out that llvm 4.0 banned
casting via static_cast. See e.g. 1e2bc42eb988 in the llvm repo what
they do.

So similarly to the above commit, change all the casts of iterators to
"&*" which is what they do in LLVM.
