Support JS Array.sort() function for sequence wrappers.

The V8 natve sort implementation calls some functions that are
incompatible with the way sequence wrappers work. In particular,
it calls an internal length() function which does not pass through
the length accessor provided by sequence wrappers, so the sort
function always thinks the array is zero length. Instead, clone the
array prototype and override the sort function with one that is
specific to sequence wrappers.
