jordan hoffmann 0e53056bc6 Clang now optimizes away this==nullptr. Calls to IsChildOf from a null UObject pointer will cause undefined behavior. This is a retroactive attempt to pad potentially dangerous calls to IsChildOf with a null check in the following directories: ...

- Plugins/BlueprintContext
- Editor/GlueprintGraph
- Editor/GraphEditor
- Editor/Kismet
- Editor/KismetCompiler
- Editor/UnrealEd/Private/Kismet2

note: if you're seeing this CL in the perforce history because you're trying to figure out why there's a null check that doesn't make sense, This is why. The goal of this CL is to preserve the behavior before IsChildOf changed rather than analyze whether that behavior makes sense. Use your best judgement
