LibJS: Add missing spec step to CompareTypedArrayElements

Browse source 
This isn't actually much of an issue because if the LHS side value is -0
and the RHS value is +0, errantly returning 0 in the comparison function
here has the same effect as correctly returning -1. In both cases, the
-0 is left on the LHS.
