Before this commit the EventEmitter methods were anonymous functions.
V8 tries to infer names for anonymous functions based on the execution
context but it frequently gets it wrong and when that happens, the
stack trace is usually confusing and unhelpful. This commit names all
methods so V8 can fall back to the method.name property.
The above gotcha applies to all anonymous functions but is exacerbated
for EventEmitter methods because those are invoked with a plenitude of
different receivers.

This reverts commit 0109a9f90a.
Also included: Port all the changes to process._makeCallback into the
C++ version. Immediate nextTick, etc.
This yields a slight boost in several benchmarks. V8 is optimizing and
deoptimizing process._makeCallback repeatedly.
