David Mosberger-Tang 458f935527 [IA64] Speed up lfetch.fault [NULL] ... This patch greatly speeds up the handling of lfetch.fault instructions which result in NaT consumption. Due to the NaT-page mapped at address 0, this is guaranteed to happen when lfetch.fault'ing a NULL pointer. With this patch in place, we can even define prefetch()/prefetchw() as lfetch.fault without significant performance degradation. More importantly, it allows compilers to be more aggressive with using lfetch.fault on pointers that might be NULL.
