Georg Schmid 94ae207bc7 [ptr-compr] Revisit transformed Phis in Decompression Elimination ... Currently, decompression elimination may reduce phis by pushing decompressions in the value inputs of the phi "down" and replacing it by a single decompression following the phi node. Because of the way that the replacement is currently done, other reducers in the same phase will not generally get a chance to revisit the modified phi. In the specific case of v8:9335 this blocked an additional optimization in CommonOperatorReducer from being applied, causing the overall load elimination test to fail. This CL fixes the replacement behavior in decompression elimination to also allow for revisitations of the modified phi node.
