Change ascents and descent calculation back to integers for now. 

As it looks like we'll need to support both the 1/60 and 1/1 implementations of FractionalLayoutUnit for the immediate future to ensure that text is rendered at the same offset and with the height regardless of the ENABLE_SUBPIXEL_LAYOUT flag. This ensures that most websites will look the same at 100% zoom regardless of the flag and also allows us to the same test expectations for the vast majority of layout tests.

Eventually we want to move those back to FractionalLayoutUnits as that will result in more correct rendering.
