RFR: 8338112: Test testlibrary_tests/ir_framework/tests/TestPrivilegedMode.java fails with release build [v3]

[SendaoYan]

> Hi all,
>  The testcase `testlibrary_tests/ir_framework/tests/TestPrivilegedMode.java` fails with release build, the test log snippet says `IR verification disabled due to not running a debug build`. So I think it's need `@requires vm.debug == true`. And ths test will fail without c2 compiler, so it also need `@requires vm.compiler2.enabled`.
> 
> The change has been verified with linux x64 release build and linux x64 fastdebug build, no risk,
