We are seeing assertion errors in some of Fuchsia's clang builders after this change was landed, the error message is:

  clang++: llvm/lib/IR/Constants.cpp:2281: static llvm::Constant *llvm::ConstantExpr::getBitCast(llvm::Constant *, llvm::Type *, bool): Assertion `CastInst::castIsValid(Instruction::BitCast, C, DstTy) && "Invalid constantexpr bitcast!"' failed.

Looks like the assertion error happens in LLVM's own codebase. It can be reproduced with reproducer: https://drive.google.com/file/d/10Cip4txCebPg2iNRt0x60WDGViSe8U_8/view?usp=sharing

Could you take a look, and if it takes a long time to fix, could you revert this change please?
