<pre>Use larger tiles when possible to reduce per-tile painting overhead
https://bugs.webkit.org/show_bug.cgi?id=154985
Reviewed by Zalan Bujtas.
Source/WebCore:
<a href="http://trac.webkit.org/projects/webkit/changeset/197541">r197541</a> inadvertently missed FrameView changes that push scrollability data
onto the TiledBacking, so didn't actually change behavior (hence the 512x512 tiles
in the failing tests).
Also remove m_tileSizeAtLastRevalidate from TileGrid; it's replaced by a simpler test.
