---------------------------
o3: issue excl. prefetch as soon as store address is available

Issue StoreAccess to acquire permission for store after translation.
In Classic: StoreAccess gets converted to HardPFExReq and shares the existing
prefetch queue. Therefore, it only affects performance if the prefetcher is
enabled in classic.

In Ruby: StoreAccess gets converted to RubyStore with NULL data field.

This work was done while Binh was an intern at AMD Research.

This patch includes bug fixes by Marc Orr.
