X87: Disable the test case for X87 since ea2cb139.

      The strong-object-set-proto test cases will throw one expected exception
      and the exception message should include the source position in the JS
      file. But crankshaft compiler does not generate the source position for
      it when creating the flow graph by default. The source position information
      is always zero. So it failed when comparing with the reference file.

      If we use crankshaft compiler on IA32 platform to run this test case, it
      has the same failure.

      we will open these test case for x87 once turbofan for X87 is enabled.
