Currently ProfilerListener channels the code events to Processor
via CpuProfiler - we don't need this indirection and can just hook
it up directly. This also makes it easier to test because we don't need
a CpuProfiler object just to test the Processor.
Drive-by cleanup:
- Remove NUMBER_OF_TYPES from CodeEventRecord as it is not used.
- Remove Isolate* parameter from AddDeoptStack and AddCurrentStack as
a Processor object is only ever for one Isolate. Store the Isolate*
on the ProfilerEventsProcessor object itself.
- Remove the default case from switch in ProcessCodeEvent().

Many parts of the old JS implementation are preserved, because

To simplify implementation, special handling of extremely sparse arrays
