[jdk16] RFR: 8258225: compiler/c2/cr6340864/TestIntVect.java runs faster in interpreter

[Nils Eliasson]

Exclude test-method from compiler/c2/cr6340864-tests.

In debug builds - the C1 method IR::verify is very costly in big methods with many blocks. The compile times explode. A sub minute test takes 35 minutes on slower machines - and these tests are run multiple times.

Some of these tests are saved by the HugeMethodLimit, but some (TestIntVect and TestLongVect) doesn't.

Please review,
Nils
