    Description

      Remove SimpleCompPolicy.

      Remove relevant parts of:
      1. InvocationCounters.
      2. Parts of the interpreter managing these counters.
      3. Remove TIERED define.

      Emulate -XX:-TieredCompilation with -XX:CompilationMode=high-only.
      Make sure JVM can build with C1 only and C2 only, add appropriate compilation policy modes.

      As a result there should be just the TieredCompilationPolicy that can function with 0 C1 threads or 0 C2 threads.
