This will add a temporary check, only to Chrome, that Windows implies SSE2 or
greater.  I'm having a difficult time figuring out what's going on in the
attached bug other than this.  It'd be nice to rule this out definitively.

If there are Chrome Windows builders not building with SSE2, this will break
those builders.  This is why I am having you review this as sheriff... it'll
only break the roll or subsequent Chrome bots, not our tree.
