FIXME: now with tree based profiling we are in the trap described above
again. It seems to be easiest to disable the optimization for time
being before the problem is either solved by moving the transformation
to the IPA level (we need the CFG for this) or the very early optimization
passes are made to ignore the const/pure flags so code does not change. */
