      [turbofan] Add support for inlining accessors into try-blocks. · 9dbafbd5
      bmeurer authored
      Previously the inlining of accessors into try-blocks (i.e. try/catch,
      try/finally, for-of, etc.) was disabled in JSNativeContextSpecialization,
      which prevented a couple of interesting optimizations, i.e. we end up
      with a LOAD_IC in optimized code for this simple example:
      
        class A { get x() { return 1; } }
        function foo(a) {
          try {
            return a.x;
          } catch (e) {
            return 0;
          }
        }
        foo(new A)
      
      This is now fixed and the accessors are properly rewired into the
      handler chain.
