Move this to "General performance" section.

I believe this refers to commit b03d196b. The "test on i386" note can
just be removed. Someone ought to test it on 32-bit i386 to see if the
same change would be beneficial there, but that's a TODO item more than
a release notes item. I doubt anyone's interested to spend time
performance testing spinlocks on 32-bit i386, though, so I think we're
going to just retain the current situation for the next decade.
