The architectures provided to skipIf / expectedFail are regular expressions (v. _match_decorator_property() in decorators.py so on Darwin systems "arm64" would match the skips for "arm" (32-bit Linux). Update these to "arm$" to prevent this, and also update three tests (TestBuiltinFormats.py, TestCrossDSOTailCalls.py, TestCrossObjectTailCalls.py) that were skipped for arm64 via this behavior, and need to be skipped or they will fail. This was moviated by the new TestDynamicValue.py test which has an expected-fail for arm, but the test was passing on arm64 Darwin resulting in failure for the CIs.
