Rebaseline tests that broke with r149156.

The rebaseline tool just grabs the platforms your rebaselining
and overwrites the current result. This can be incorrect if
one of the fallback platforms depended on this result, e.g.
if you rebasline a test on windows, the linux bot might start
failing because it matched the old windows result and not the
new one.

Remove allocators

Patch by Laszlo Gombos https://codereview.chromium.org/13963021/

YARR was the last client of the allocators. Now that YARR
is removed (r149026) the allocators can be removed as well.
