Revert of Optimize QuadF's PointIsInTriangle function (patchset #3 id:40001 of https://codereview.chromium.org/458173002/)

Reason for revert:
Caused perf regressions: https://code.google.com/p/chromium/issues/detail?id=404968

Original issue's description:
> Optimize QuadF's PointIsInTriangle function
>
> PointIsInTriangle() is still the hotspot of many CSS animation cases.Take Nexus10 with latest chromium build for example:
> 4.0%  case: poster-circle.html
> 1.5%  case: morphing-cubes.html
>
> This patch changes the algorithm of testing "Point In Triangle".
> 1. Using double-precision float point.
> 2. A much readable algorithm.
> 3. Better performance due to remove 2 div operation
