events: avoid emit() eager deopt
This commit makes sure EventEmitter.emit() doesn't get deoptimized by
V8. The deopt happens when accessing out of bound indexes of the
`arguments` object.
This issue has been raised here: #10323 and this specific case might
become a more serious performance issue in upcoming V8 releases.
