0667160b11 Fix optimisation of shadowed rest parameters 
The arguments of a function would be unnecessarily copied if there was
a nested function that had a parameter with the same identifier as the
rest parameter for the outer function. This checks the scope of the
parameter is correct before deoptimising.
