Micros-Crypto performance regressions in 12+6 need investigation

There are noticeable performance regressions on both Linux and Windows that need to be investigated. They are each AES related:

• micro.benchmarks.crypto.small.AESBench.decrypt-algorithm:AES_CBC_NoPadding-dataSize:1024-keyLength:128-provider:
      LXS: approx. -18%
      WXS: approx. -3%

• micro.benchmarks.crypto.small.AESBench.decrypt-algorithm:AES_ECB_NoPadding-dataSize:1024-keyLength:128-provider:
      LXS: approx. -8%
      WXS: approx. -4%

• micro.benchmarks.crypto.small.AESGCMBench.decrypt-algorithm:AES_GCM_NoPadding-dataSize:1024-keyLength:128-provider:
      LXS: approx. -3%
      WXS: approx. -2%

The regressions reproduce when ran on the same machine (ie, triage).
The regressions reproduce when ran on a different machine (ie, re-traige).
A JVMswap run indicates the cause is in the JDK (ie, not the JVM).
