Align SameSizeAsFillLayer with FillLayer

Align SameSizeAsFillLayer with FillLayer

After http://crrev.com/35303002/ added a bit in FillLayer, it was
discovered that SameSizeAsFillLayer was slightly out-of-date (by 11
bits). Remove ambition to track the number of used bits in each bit
field since it easily goes out-of-date and doesn't serve a useful
purpose.

No interest in this? I felt a little bad for making it more out-of-sync in
https://codereview.chromium.org/35303002, but perhaps we won't change this until
we roll over the next 32-bit limit?

I think I'd rather just see the specified bits there go away since they clearly
aren't having the effect they suggest.

Agreed. Patch updated.

Julien, what do you think? There are a number of other places
(SameSizeAsNodeRareData, SameSizeAsFloatingObject, etc) where the count has
rotted or is just wrong. Most SameSize* just use an |unsigned bitfield| though.

Something to care about or only fix when we have to touch the code for other
reasons?

Works for me. LGTM.
