convert iterators using static_cast

Newer versions of LLVM do not allow to implicitly cast iterators to
pointers where they point. So convert all such uses to explicit
static_cast, the same as LLVM code does.

Otherwise we see errors like:
lib/Core/Executor.cpp:548:15: error: no viable conversion from 'Module::iterator' (aka 'ilist_iterator<llvm::Function>') to 'llvm::Function *'
    Function *f = i;
