In scope of SL-13740 work, this reverts commit 1935d25c.

LLHUDObject has a lot of deriveds stored as LLPointer<LLHUDObject>, no-virtual destructor is unlikely to be cause of the crash, but might be related

LLVOAvatars and derived classes appear to be stored as LLPointer<LLViewerObject> in a lot of cases, so non-virtual ~LLViewerObject() might be triggered by LLPointer and end up not cleaning sInstances in some cases (animeshes specific?), thus causing broken pointers in sInstances.
