  X87: Fix the sqrt precision issue.

    In order to resolve the sqrt precision issue described in https://codereview.chromium.org/1425763002/.
    we change the implementation of CreateSqrtFunction() implementation of X87 so that the optimize compiler
    and full-compiler implementation are unified.
