last change	Handle branch delay-slot instruction that falls on the next page correctly. - Generate the right end PC in the first place (sh4trans.c) - Allow blocks to be marked as both entry point + continuation, and specifically handle invalidation when first entry of a page is a continuation == flush previous page as well.
