Fix perf regression for simple startup benchmarks in new SymbolTable

    Details

      Description

      Switching SymbolTable implementation to use concurrent hash table shows minor (~5%) regression for trivial startup benchmarks.

      Need to figure out what exactly is going on (old table was practically sync free when JVM starts up single threaded, but new one has some bookkeeping to do always) and get the performance back up.
