minor microVU rec changes 

note to pcsx2 users: for those that still don't know, these are new VU recompilers i'm working on. They're not working yet, and won't be for at least a few months. So don't expect noticeable changes when i update microVU stuff, since currently they're not being used (when they're in a semi-working/usable state, i'll be sure to put a note in the revision message ;p)
