Instead of checking e.g. the first access on every touched page, we should check the actual access, otherwise we might get false positives when Low Address Protection (LAP) is active. As probe_write() can only deal with accesses to one page, we have to loop. Use i64 for the length, although not needed - easier to reuse TCG temps we already have in the translation functions where this will be used. Also allow it to be used from other helpers.
