This enables unwinders to step past that frame on architectures that don't use DWARF unwinding (such as armv7), e.g. when debugging. The problem should theoretically be architecture-agnostic, but according to https://discourse.llvm.org/t/51633/2 it gets masked on architectures that use DWARF unwind info.
