One alternative: I can simply do away with the remapping and just
allocate the bits for the new constants (EFD_CLOEXEC) to match those of
the O_* constants.  This means we can still reuse the low bits which
aren't available in the O_* constants.  It means, though, that the
constants are architecture specific since O_CLOEXEC, for instance, has
different values for different architectures.
