I don't have a copy of Muchnick's book at hand right now, but the
paragraph at the top of the file is definitely still accurate, the
local/global copy propagation pass split is unchanged, only the dataflow
propagation algorithm used in order to compute the live sets required as
input for the global copy propagation pass is affected by this patch.
