Second attempt to fix a null pointer reference in deallocators of

built-in types (the first was in revision 21877).  When an exception
has raised within from the __init__ method of a user-defined class
derived from a built-in type (e.g., UnaryPredicate0D and
BinaryPredicate1D), some member variables of the base type are
left uninitialized, leading to a null pointer reference in the
"__dealloc__" function in the base type.  To avoid this, pointer
checking was added in the deallocators of those built-in types that
can be used to define a subclass by a user.
