cc: Fix rasterize and record micro to only check layers with content.
This patch replaces a check that checked whether the layer draws content
with a check to see if the layer can have tilings. There are more
conditions that can cause the layer not to have tilings (solid color,
no recordings). Some of those situations can cause crashes if we
create tilings anyway, so the fix is to check CanHaveTilings directly.
