MemoryBuiltins: Properly guard ObjectSizeOffsetVisitor against cycles in the IR.
The previous fix only checked for simple cycles, use a set to catch longer
cycles too.
Drop the broken check from the ObjectSizeOffsetEvaluator. The BoundsChecking
pass doesn't have to deal with invalid IR like InstCombine does.
