The compiler builtins are now available on all supported compilers, so use them instead. (The compiler builtins are also unnecessarily ugly, but that's a more manageable level of ugliness.)

The result is that these tests fail randomly depending on when interrupts happen. Detect when this happens and let the test pass.
