An alloca in an unreachable block would shortcircuit with Undef, but with type `Type`, rather than type `*Type` (i.e. a plain value, not a pointer) but it is expected to return a pointer into the stack, leading to confusion and LLVM asserts later. Similarly, attaching the range metadata to a Load in an unreachable block makes LLVM unhappy, since the Load returns Undef. Fixes #7344.
