Right now, we have Value::getPointerDereferenceableBytes() and Value::getPointerAlignment() that allow to query these properties for a value. However, neither does any "reasoning" that would require looking at other values, e.g., they do pure local lookups. To do actual reasoning we have the "isDereferenceableAndAlignedPointer()"-family of functions in Loads.h. A...

You need to configure with --enable-llvm. (It would still be nice if V1DI_pointer_node was defined; I'll take a look at that.)
