[Lldb-commits] [lldb] r216032 - Add an accessor to ValueObject that determines if the object represents a base class, and also returns the depth of base-class-ness. For instance if one has class C : public B {} class B : public A {}, the value for A nested in B nested in C would be a base class of depth 2
