Reviewed by Tim Horton.

FrameView::repaintFixedElementsAfterScrolling() didn't do any repainting, and didn't
just apply to fixed elements. Rename it to updateLayerPositionsAfterScrolling().

updateFixedElementsAfterScrolling() was also confusingly named; rename it
to updateCompositingLayersAfterScrolling().
