ir3: make fullsync sync after shared writes

Browse source 
fullsync would only sync after cat4/5/6 instructions. However, since the
introduction of scalar ALU, we also need to sync after writes to shared
registers. This commit fixes this by using the is_ss/sy_producer
helpers. This should also catch all cases where (ss) is need for WAR
hazards.
