Coding standards say: "Tests for true/false, null/non-null, and zero/non-zero should all be done without equality comparisons."

I cannot recall if this was due to an issue with LIKELY on some platforms. If all the bots are green though, feel free to land this.

Windows bot has been broken for a week now, and if there was an issue with LIKELY I bet it was on Windows. :(

Would you mind if I simply get rid of all the uses of LIKELY in this patch as well? I'm pretty sure it's hocus pocus. http://stackoverflow.com/a/1851905 has a good explanation....

That comment also says:

"Besides the useless branch hint for the predictor, __builtin_expect has its use, the compiler may reorder the code to improve cache usage or save memory."

OK, I'll keep LIKELY then, although if Intel recommends against using it I think it's _likely_ safe to remove. If it's a problem for WinCairo I guess we'll find out when the EWS is fixed... if that even is a WinCairo bot, I think it's probably AppleWindows....

I don't understand why webkit-patch and the commit-queue can't handle changelog updates anymore. I don't see any changes to the tools, and I'm not doing anything differently....
