bbi 48980.ll reproducer

llvm commit: 7025687799

Reproduce with:
opt -S -o - bbi-48980.ll -inline

Result:
opt: ../lib/IR/Constants.cpp:1794: static llvm::Constant
*llvm::ConstantExpr::getCast(unsigned int, llvm::Constant *, llvm::Type *,
bool): Assertion `CastInst::castIsValid(opc, C, Ty) && "Invalid constantexpr
cast!"' failed.

This seems to be old, I've reproduced it with old saved builds from November
2016.
