Cache events and listeners objects where possible and loop over Object.keys() instead of using for..in. These changes alone give ~60-65% improvement in the ee-add-remove benchmark. The changes to EventEmitter.listenerCount() gives ~14% improvement and changes to emitter.listeners() gives significant improvements for <50 listeners (~195% improvement for 10 listeners). The changes to emitter.emit() gives 3x speedup for the fast cases with multiple handlers and a minor speedup for the slow case with multiple handlers. The swapping out of the util.is* type checking functions with inline checks gives another ~5-10% improvement.
