Fold the SB-1 specific implementation of clear_page/copy_page in the generic version, and rewrite that one in tlbex style. The immediate benefits: - It converts the compile-time workaround for SB-1 pass 1 prefetches to a more efficient run-time check. - It allows adjustment of loop unfolling, which helps to reduce the number of redundant cdex cache ops. - It fixes some esoteric cornercases (the cache line length calculations can go wrong, and support for 64k pages without prefetch instructions will overflow the addiu immediate). - Somewhat better guesses of "good" prefetch values.
