You need to include llvm/Instructions.h to get the definition of CallInst.

FWIW, this:

  CallInst* callInst = dyn_cast<CallInst>(&*basic_block_iterator_1);

is equivalent to this:

   CallInst* callInst = dyn_cast<CallInst>(basic_block_iterator_1);

if basic_block_iterator_1 is a BasicBlock::iterator.
