Original Commit Message:

    The 32-bit value is zero-extended to pointer size, which is a no-op on
    32-bit systems. The operation changes nothing about the signedness of
    the value, so the old name was a bit misleading.

    We also provide one unified no-op implementation for all 32-bit systems.
