Benchmarks to check migration impact to j.l.invoke and j.l.reflect.Proxy performance

[-]

Hello Adam,
Last time, you said that a major obstacle to the migration of Proxy
and MethodHandle ASM code to Classfile API is the performance
degradation. I wish you can share how you measured the impact of
migration, so that I can try for myself and see the performance
bottlenecks.
