Hi,

The following starts crashing with this patch:

  opt -passes='loop-mssa(indvars,indvars)' -o /dev/null bbi-63564.ll

We hit this assert:

  opt: ../include/llvm/Support/Casting.h:104: static bool llvm::isa_impl_cl<llvm::Instruction, const llvm::Value *>::doit(const From *) [To = llvm::Instruction, From = const llvm::Value *]: Assertion `Val && "isa<> used on a null pointer"' failed.

F20788344: bbi-63564.ll <https://reviews.llvm.org/F20788344>
