Several jvmci tests failed on riscv after JDK-8329982

For now, jvmi feature is only *** partially *** supported on riscv by JDK-8290154.

Following jvmci tests failed on this platform after JDK-8329982.

  TEST: compiler/jvmci/jdk.vm.ci.code.test/src/jdk/vm/ci/code/test/DataPatchTest.java
  TEST: compiler/jvmci/jdk.vm.ci.code.test/src/jdk/vm/ci/code/test/MaxOopMapStackOffsetTest.java
  TEST: compiler/jvmci/jdk.vm.ci.code.test/src/jdk/vm/ci/code/test/NativeCallTest.java
  TEST: compiler/jvmci/jdk.vm.ci.code.test/src/jdk/vm/ci/code/test/SimpleCodeInstallationTest.java
  TEST: compiler/jvmci/jdk.vm.ci.code.test/src/jdk/vm/ci/code/test/SimpleDebugInfoTest.java
  TEST: compiler/jvmci/jdk.vm.ci.code.test/src/jdk/vm/ci/code/test/VirtualObjectDebugInfoTest.java

From the error message, it seems that nmethod entry barrier is missing for these tests:
