Jun Bum Lim f5fb3d745d [LICM] sink through non-trivially replicable PHI ... Summary: The current LICM allows sinking an instruction only when it is exposed to exit blocks through a trivially replacable PHI of which all incoming values are the same instruction. This change enhance LICM to sink a sinkable instruction through non-trivially replacable PHIs by spliting predecessors of loop exits.
