peterwmwong 986aa36b1f [builtins] Add Array.p.join fastpath for single element array.
This is resurrecting an optimization from the pre-torque version.
Avoid allocating another sequential string for the result when there's only one
element, just return the ToString-ed element.  This not only saves time writing
to this destination string, but also reduce GC pressure.

The System Health Memory Benchmark (load:media:google_images) exposed this missing
optimization with a 15% regression in memory usage.  Very large external strings
were being copied into V8's heap as sequential string.
