    Implement fastpath for proxy trap getPrototypeOf · 4e17a6be
    Z Nguyen-Huu authored
    ObjectGetPrototypeOf and ReflectGetPrototypeOf are now Torque builtins (previously CPP) and the Proxy path is implemented completely in Torque while everything else calls into runtime (and is thus a bit slower than previously).
