commit-bot@chromium.org a90c680386 Turn on quilt mode in DM. 
- Rename TileGrid -> Quilt to avoid the name overload.
  - Tag all failing GMs with kSkipTiled_Flag.

You may be wondering, do any GMs pass?  Yes, some do!  And that trends towards all of them as we increase --quiltTile.

Two GMs only fail in --quilt mode in 565.  Otherwise all GMs which fail are skipped, and those which don't fail aren't. (The 8888 variants of those two GMs are skipped even though they pass.)
