    [Torque] Move some TypedArray builtins to Torque · 40c9cce4
    Mike Stanton authored
    This CL moves the following builtins from CSA to Torque:
    
    TypedArray.prototype.forEach
    TypedArray.prototype.reduce
    TypedArray.prototype.reduceRight
    
    A space-saving decision was made in the design -- instead of emitting
    versions of the central loop for each ElementsKind, a function
    pointer which knows how to read from the appropriate TypedArray
    ElementsKind is constructed at the outset, and passed into the
    loop. This enormously reduces codesize for the TypedArray builtins.
    We'll have to see if the overhead of the builtin call affects
    performance too adversely.
