RFR: 8344556: [Graal] compiler/intrinsics/bmi/* fail when AOTCache cannot be loaded

[Ioi Lam]

When running with 


$ make test-only JTREG=AOT_JDK=twostep \
  TEST_VM_OPTS='-XX:+UnlockExperimentalVMOptions -XX:+UseGraalJIT' \
  TEST=open/test/hotspot/jtreg/compiler/intrinsics/bmi/TestBlsmskL.java


One of the the -Xint or -Xcomp VM launched by these tests will not be able to load the AOT cache (due to [JDK-8358738](https://bugs.openjdk.org/browse/JDK-8358738) -- at this point, we are not sure if this behavior is intended or not).

Regardless on the decision about  [JDK-8358738](https://bugs.openjdk.org/browse/JDK-8358738) , we should make the bmi tests more resilient by filtering out AOT error logs, since the purpose of thethe bmi tests are for testing intrinsics, not AOT.
