DescriptionTypedArray and ArrayBuffer support for @@species
This patch improves ArrayBuffer and TypedArray subclassing by adding
support for @@species and constructing outputs to certain methods
by creating an instance of the constructor determined by the
SpeciesConstructor algorithm, rather than fixed to a superclass or
naively the constructor. The new behavior is enabled by the
--harmony-species flag. Care is taken to not significantly change the
observable behavior when the flag is off. Previously, TypedArrays
already supported subclassing by reading the constructor of the
receiver, but ArrayBuffers did not, and this old behavior is
preserved and tested for, to avoid a multi-stage upgrade path and keep
things simple for users.
