Testcase

The attached test case fails compilation with the following error:
clang++: /home/qon/tmp9/llvm-project/llvm/lib/IR/Instructions.cpp:2917: static
llvm::CastInst* llvm::CastInst::Create(llvm::Instruction::CastOps,
llvm::Value*, llvm::Type*, const llvm::Twine&, llvm::Instruction*): Assertion
`castIsValid(op, S, Ty) && "Invalid cast!"' failed.
PLEASE submit a bug report to https://bugs.llvm.org/ and include the crash
backtrace, preprocessed source, and associated run script.
