r75229 fixed CALL_PURE not throwing away caches of getfield/setfield in case it's 
rendered (and not constant-folded away). This seems to be a correct fix if we 
agree that CALL_PURE might have observable side effects if it's called, however, 
it should always return the same value for the same args.
