X87: disable the regress-crbug-242924 test case for x87.

  The reason:
  Similar to the CL 31552 (https://codereview.chromium.org/1419573007).

  The CL 33972 (https://codereview.chromium.org/1698783002) optimized some JS function in regress-crbug-242924 test case by TurboFan compiler.

  But it will hit the known issue that X87 will change a sNaN to qNaN by default. And then it will fail when comparing the source (sNaN) Hole NaN and
  the result (qNaN) which was expected to be a (sNaN) Hole NaN too.
