Binary search through ArtFields to match by name.
Commit bfa3ed0ad988e1da13626ddbaf6dcae0c58ea79e in art preserves
the original field order for ArtFields, and they will therefore be
sorted by name. For classes with large numbers of static and instance
fields, a binary search is obviously much faster.
Before:
Scenario{vm=app_process, trial=0, benchmark=GetInstanceField} 275460.26 ns; σ=19.75 ns @ 3 trials
Scenario{vm=app_process, trial=0, benchmark=GetStaticField} 661690.26 ns; σ=6340.84 ns @ 5 trials
After:
Scenario{vm=app_process, trial=0, benchmark=GetInstanceField} 3502.96 ns; σ=32.15 ns @ 3 trials
Scenario{vm=app_process, trial=0, benchmark=GetStaticField} 6579.58 ns; σ=40.49 ns @ 3 trials
