The `update_cc_test_checks.py ` script iterates over clang AST generated by the provided runline. 
Since the stub variant are not present in the AST (emitted to IR), the script does not generate check lines to detect the stub variants, namely, `__clang_ocl_kern_imp_callee_kern` and `__clang_ocl_kern_imp_ext_callee_kern`
