  [lldb] Try harder to find the __NSCFBoolean addresses

It looks like recent CoreFoundation builds strip the non-public symbol
that we were looking for to find the 2 boolean "classes". The public
symbol is of course there, and it contains the address of the private
one. If we don't find the private symbol directly, go through a memory
read at the public symbol's location instead.
