Ben Noordhuis 8350f3a3a2 buffer: optimize Buffer#toString() ...

Break up Buffer#toString() into a fast and slow path.  The fast path
optimizes for zero-length buffers and no-arg method invocation.

The speedup for zero-length buffers is a satisfying 700%.  The no-arg
toString() operation gets faster by about 13% for a one-byte buffer.

This change exploits the fact that most Buffer#toString() calls are
plain no-arg method calls.  Rewriting the method to take no arguments
means a call doesn't go through an ArgumentsAdaptorTrampoline stack
frame in the common case.
