RFR: 8360936: Test compiler/onSpinWait/TestOnSpinWaitAArch64.java fails after JDK-8359435 [v10]

[Evgeny Astigeevich]

> Test compiler/onSpinWait/TestOnSpinWaitAArch64.java needs debug info to identify a position of spin wait instructions in generated code. The test switched to use `XX:CompileCommand=print` instead of `XX:+PrintAssembly` to have assembly only for a tested Java method. In release builds  `XX:+PrintAssembly` prints out debug info but `XX:CompileCommand=print` does not.
> 
> This PR reimplements the test to parse instructions and to check them. The test does not rely on debug info anymore.
> 
> Tested on Linux and MacOS with and without hsdis:
> - Fastdebug: test passed
> - Slowdebug: test passed.
> - Release: test passed.
