LGTM

I'm not very happy with this CL, since it forces us to carry around a lot of
100P baggage just to make favicon sync work.  I would really like to roll this
back someday, so I want us to find a different long-term solution to the favicon
problem.

To thakis for owner review.

Note that this CL only changes iOS code and has no impact on any other
platforms.

What do you need this for? The CL description doesn't say, and there's nothing
in the BUG= line either.

lgtm with a comment that explains why you need 1x on retina ios devices. If you
think rohit's wish to undo this eventually is realistic, add a todo and a
tracking bug for that.

File ui/base/layout.cc (right):

https://codereview.chromium.org/11293147/diff/1/ui/base/layout.cc#newcode76
ui/base/layout.cc:76: // 100P is always a supported scale factor.
Explain why this is enabled on iOS, which technically wouldn't need it.
