[PATCH] D36947: [x86] Teach the "generic" x86 CPU to avoid patterns that are slow on widely used processors.

This seems really uncontroversial as it essentially just avoids some patterns. Going ahead and landing for now. Happy to revisit or enhance this as desired by others of course.

Thanks for the reviews so far (and glad you mentioned AMD processors Eric!)
