[CGP] Fix handling of null pointer values in optimizeMemoryInst The current way that trivial addressing modes are detected incorrectly thinks that null pointers are non-trivial, leading to an infinite loop where we keep duplicating the same select. Fix this by aware of null when deciding if an addressing mode is trivial.
