Sathya Gunasekaran 15c227befb [runtime] Fix TypedArrayPrototype protector cell checks 
Previously, we were looking up the prototype of the receiver and
checking that against %TypedArrayPrototype% before invalidating the
protector cell.

This is incorrect as it's possible to patch the prototype and then
change the constructor property, bypassing this check.

This CL adds a new instance type to prototype of all TypedArray
constructors and checks the receiver against this instance type.
