qHash: provide the long double overload on Darwin systems

Browse Source 
Commit c0791ac76ec7cfdc3945efa67a6f72ee3623413c didn't explain why it
was #ifdef'ed out. It's just an alias for double. Maybe compilers at the
time used to complain if you used it, but I can't make Apple's clang
produce a warning now.
