      zhengxing.li authored 
        port a94d6d6e (r33108)

  original commit message:
  The mode requires an extra register, and since we aren't supporting it now, we can dispense with it.

      [turbofan] Ship TurboFan with new.target references. · 020b419c
      bmeurer authored 
      This correctly marks functions containing a new.target reference as
being disabled with Crankshaft, which would have bailed out anyways.
Also note that this will trigger TurboFan for such functions and hence
widens the TurboFan intake valve.

      Add Array support for @@species and subclassing · 6e962237
      littledan authored 
      This patch implements @@species, guarded behind the --harmony-species
flag, on Arrays. Methods which return an Array will instead return
the appropriate instance based on the ArraySpeciesCreate algorithm.
The algorithm is implemented in C++ to get access to realm information
and to implement some Array methods in C++, but it is also accessed
from JavaScript through a new runtime function. A couple interactive
Octane runs show no performance regression with the flag turned off,
but turning --harmony-species on will surely have a significant
regression, as Array methods now heavily use ObjectDefineProperty.

      X87: [wasm] Change the test case for Run_WasmCall_Float32Sub · 48bc9425
      zhengxing.li authored 
        The reason is same as the CL #31808 (issue 1430943002, X87: Change the test case for X87 float operations), please refer: https://codereview.chromium.org/1430943002/

  Here is the key comments from CL #31808
  Some new test cases use CheckFloatEq(...) and CheckDoubleEq(...) function for result check. When GCC compiling the CheckFloatEq() and CheckDoubleEq() function, those inlined functions has different behavior comparing with GCC ia32 build and x87 build.
  The major difference is sse float register still has single precision rounding semantic. While X87 register has no such rounding precsion semantic when directly use register value.
  The V8 turbofan JITTed has exactly same result in both X87 and IA32 port.

  So we add the following sentence to do type case to keep the same precision for Run_WasmCall_Float32Sub.
  Such as: volatile float expect = *i +/- *j; // *i +/- *j, etc.
