[PATCH] D45900: CodeGen: Fix invalid bitcast for lifetime.start/end

Oh, I see, it's not that the lifetime intrinsics don't handle pointers in the alloca address space, it's that we might have already promoted them into `DefaultAS`.

Do the LLVM uses of lifetime intrinsics actually look through these address space casts?  I'm wondering if we might need to change how we emit the intrinsics so that they're emitted directly on (bitcasts of) the underlying allocas.
