RFR: 8351952: [IR Framework]: allow ignoring methods that are not compilable

[Emanuel Peter]

With the Template Framework, I'm generating IR tests randomly. But random code can always hit bailouts in compilation, and make code not compilable any more. We should have a way to disable this check, and just gracefully continue to execute the tests.

To allow a single test method to be `not compilable`:
https://github.com/openjdk/jdk/blob/ce40f1402387f75ea8627883979e3cbf63480941/test/hotspot/jtreg/testlibrary_tests/ir_framework/tests/TestNotCompilable.java#L160-L161

To allow all test methods to be `not compilable`:
https://github.com/openjdk/jdk/blob/ce40f1402387f75ea8627883979e3cbf63480941/test/hotspot/jtreg/testlibrary_tests/ir_framework/tests/TestNotCompilable.java#L140-L144

See also this documentation in the code:
