Revert 74571 - Use SSE2 block differ for chromoting
We have the SSE2 lying around in the tree just never being used. This will
allow us to use it.
A number of Windows bots have gone red in media_tests on the waterfall:

http://build.chromium.org/p/chromium/builders/XP%20Tests%20%281%29/builds/501/steps/media_unittests/logs/stdio
This seems to be related to r74571. So am reverting to see.
BUG=None
TEST=Chromoting to a host machine and the diff will work correctly
