Can someone please explain the value of this warning about the type not enabled for a target?  E.g. flang-new fails on a very simple program with real*10 on arm, so should this warning be turned into an error?

```
program main
  real(10) :: x
  x = 1.0_10
  print *, x
end program main
```

```
flang-new: .../llvm/lib/CodeGen/SelectionDAG/SelectionDAG.cpp:1736: llvm::SDValue llvm::SelectionDAG::getConstant(const llvm::ConstantInt&, const llvm::SDLoc&, llvm::EVT, bool, bool): Assertion `Elt->getBitWidth() == EltVT.getSizeInBits() && "APInt size does not match type size!"' failed.
