Revert of X87: disable the regress-undefined-nan test case for x87. (patchset #1 id:1 of https://codereview.chromium.org/1414733004/ )

Reason for revert:
because of merge mistake, "regress/" is missed when skipping one test case for X87.

 "regress/" will be added when relanding it.

Original issue's description:
> X87: disable the regress-undefined-nan test case for x87.
>
>   The reason is when native_context_specialization flag is ture, X87 turbofan
>   will hit the known issue that X87 will change a sNaN to qNaN by default. And
>   then it will fail when bit-comparing the source (sNaN) and the result (qNaN).
