      Add fast path for proxy with preventExtensions trap · 8e0ef9b9
      Z Nguyen-Huu authored
      ObjectPreventExtensions and ReflectPreventExtensions 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).
      
      Perf improvement in micro-benchmark JSTests/Proxies
