second step in dlist optimizations: test the hashes only when the cpu could change the contents of the dlist, this is after it been processed, or at frame finish.
this is marcos idea so the credits go to him. please test the broken games in my last commits to see if this solve all the issues. git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@7114 8ced0084-cf51-0410-be5f-012b33b47a6e
