  [libc++][TZDB] Fixes reverse time lookups.

Testing with the get_info() returning a local_info revealed some issues in
the reverse lookup. This needed an additional quirck. Also the skipping
when not in the current continuation optimization was wrong. It prevented
merging two sys_info objects.

  Log Message:
  -----------
  [libc++] Makes saturation functions privately available.

These functions are useful in the implementation of the time zone
database. So expose them with private names.

The functions could be exposed before C++ 20, but since libc++ is mostly
C++ 17 complete it seems less useful to allow earlier.
