This is actually relatively easy to fix, at least for the nodes that  
are type-homogeneous.  You just need to change the R/W flags to be one  
flag per field instead of one flag per node, and make the  
corresponding changes to compute them (on loads and stores), and  
propagate them (on node merges).
