node: improve nextTick performance This commit uses separate functions to isolate deopts caused by try-catches and avoids fn.apply() for callbacks with small numbers of arguments. These changes improve performance by ~1-40% in the various nextTick benchmarks.

benchmark: cover more nextTick() code The benchmarks for `process.nextTick()` do not cover the `default` case in the internal code's `switch` statement where the callback receives more than 3 arguments. Modify two of the benchmarks to include this condition.
