peterwmwong 952c097679 [builtins] Port Array.p.join to Torque. 
This also includes ports of Array.p.toString and Array.p.toLocaleString.
Many parts of the old JS implementation are preserved, because
TypedArray.p.join still relies on it.  These will be removed once
TypedArray.p.join is ported to Torque.

To simplify implementation, special handling of extremely sparse arrays
has been removed.

Performance improvements vary by array size, elements, and sparse-ness.
Some quick numbers and graphs are here:
