Make RefCount pointers behave more like regular pointers.

Allow default (but safe, thanks to C++11) conversion of RefCount
pointers to bool. This helps keep the code succinct, minimizes changes
during conversion of reference counting pointers to/from other pointer
types, and avoids nullptr/NULL differences.
