Original Commit Message:

    We can share almost all of the architecture-specific builtin code with super-call-with-spread.

    Info to port-writers: The code in CheckSpreadAndPushToStack has changed slightly
    from what was in Generate_ConstructWithSpread, in that we take the length of the
    spreaded parameters from the JSArray rather than the FixedArray backing store.

Use LoadB here will fix the endian issue.
