The test checks that an array of Obj-C literal integers (e.g. `@1`) gets a UBSan warning when cast to an NSString, however the actual concrete Obj-C class of literal integers doesn't always need to be __NSCFNumber. Let's relax the test expectations to allow NSConstantIntegerNumber. Which exact subclass of NSNumber is used is not actually important for the test (the test is just checking that the invalid cast warning is thrown).
