  Log Message:
  -----------
  [lldb] Reland "Use translated full ftag values"

Translate between abridged and full ftag values in order to expose
the latter in the gdb-remote protocol while the former are used by
FXSAVE/XSAVE...  This matches the gdb behavior.

The Shell/Register tests now rely on the new behavior, and therefore
are run on non-Darwin systems only.  The Python (API) test relies
on the legacy behavior, and is run on Darwin only.
