After JDK-8355293 , compiler/vectorization/runner/BasicIntOpTest.java fails when using RVV without using zvbb.
The reason for the error is that PopCountVI on RISC-V requires zvbb, not just rvv.

Error log is as follows：
```
Failed IR Rules (1) of Methods (1)
----------------------------------
1) Method "public int[] compiler.vectorization.runner.BasicIntOpTest.vectorPopCount()" - [Failed IR rules: 1]:
   * @IR rule 1: "@compiler.lib.ir_framework.IR(phase={DEFAULT}, applyIfPlatformAnd={}, applyIfCPUFeatureOr={"asimd", "true", "avx2", "true", "rvv", "true"}, counts={"_#V#POPCOUNT_VI#_", ">0"}, failOn={}, applyIfPlatform={}, applyIfPlatformOr={}, applyIfOr={}, applyIfCPUFeatureAnd={}, applyIf={}, applyIfCPUFeature={}, applyIfAnd={}, applyIfNot={})"
     > Phase "PrintIdeal":
       - counts: Graph contains wrong number of nodes:

           - Failed comparison: [found] 0 > 0 [given]
           - No nodes matched!

   - To only run the failed tests use -DTest, -DExclude,
     and/or -DScenarios.
   - To also get the standard output of the test VM run with
     -DReportStdout=true or for even more fine-grained logging
     use -DVerbose=true.
