Turbofan is a lot slower than Crankshaft at constructing TypedArrays,
because we always go to the C++ builtin. Port the builtin to CSA
to improve performance, and to clean up the implementation, which is
split across multiple files and pieces at the moment.

This CL increases the performance with --future to roughly the same
as with crankshaft.
