  Log Message:
  -----------
  [clang] Migrate away from PointerUnion::dyn_cast (NFC) (#225319)

Note that PointerUnion::dyn_cast has been soft deprecated in
PointerUnion.h:

  // FIXME: Replace the uses of is(), get() and dyn_cast() with
  //        isa<T>, cast<T> and the llvm::dyn_cast<T>

We must use dyn_cast_if_present here because the operands can be null,
which I have verified with assert(!isNull()) on check-clang.
