[patch] alias.c: propagate information in RPO order on the CFG

Hello, This both speeds up and improves RTL alias analysis by propagating the alias chains information in a visit in topological order of the CFG. Perhaps unsurprisingly, this is motivated again by PR middle-end/54146, where I noticed that the loop in init_alias_analysis terminated because the it
