[benchmark] Benchmark for switch on various constant types
AOT:
SwitchFSM.enum(RunTime): 29.549523327947906 us.
SwitchFSM.int(RunTime): 37.73789702628717 us.
SwitchFSM.class(RunTime): 138.6418530572675 us.
SwitchFSM.string(RunTime): 797.54075 us.
dart2js+V8:
SwitchFSM.enum(RunTime): 31.484299349840917 us.
SwitchFSM.int(RunTime): 26.022895908416366 us.
SwitchFSM.class(RunTime): 91.67433302667894 us.
SwitchFSM.string(RunTime): 92.31338451577098 us.
Both AOT and dart2js are 'good at' switches on enum values.
When compiled with --enable-experiment=records,patterns:
AOT:
SwitchFSM.enum(RunTime): 141.75470079359405 us.
SwitchFSM.int(RunTime): 145.25322604030737 us.
SwitchFSM.class(RunTime): 138.45460840662005 us.
SwitchFSM.string(RunTime): 797.226 us.
dart2js+V8:
SwitchFSM.enum(RunTime): 98.93787283573403 us.
SwitchFSM.int(RunTime): 29.459852700736498 us.
SwitchFSM.class(RunTime): 98.62184338405162 us.
SwitchFSM.string(RunTime): 92.035889371936 us.
There is work to be done to recover the performance.
