1;; This test makes sure a static var is not selected as a callee target (it will 2;; have a different GUID). Similarly, ensure that a callee GUID annotated from a 3;; sample pgo profile that matches a global variable GUID (either due to code 4;; changes or a hash collision), does not get considered for importing.
