RFR: 8350460: org.openjdk.bench.vm.floatingpoint.DremFrem JMH fails with -ea [v2]

[Eric Caspole]

> The normal SQE process runs all the repo JMH with -ea to get the last bit of extra testing. This DremFrem JMH contained some asserts that would always fire on the correct answer, disturbing this normal SQE process. I removed a lot more asserts from this JMH  which seemed to make it more of a SQE test than a benchmark. We would prefer to keep benchmarks as benchmarks as much as possible and not creep into tests.
