RFR: 8350049: [JMH] Float16OperationsBenchmark fails java.lang.NoClassDefFoundError

[SendaoYan]

Hi all,

The newly added JMH tests 'org.openjdk.bench.jdk.incubator.vector.VectorMultiplyOptBenchmark' fails "java.lang.NoClassDefFoundError: jdk/incubator/vector/Float16" by below test command:


make test MICRO="FORK=1;WARMUP_ITER=2" TEST="micro:org.openjdk.bench.jdk.incubator.vector.VectorMultiplyOptBenchmark.test_bm_pattern1"


The `@Fork(jvmArgsPrepend = ..)` in microbenchmarks should replaced as `@Fork(jvmArgs = ..)` since [JDK-8343345](https://bugs.openjdk.org/browse/JDK-8343345). Change has been verified locally, test-fix only, no risk.
