I have been looking at instruction cache invalidation, related to bug 73300.  It is very difficult to tell when cacheFlush() needs to be invoked, and when it is not.  What is the right thing to do?  Make more consistent use of DFG::RepatchBuffer ?

I am happy to take a look at adapting old code to use the repatchbuffer, if that's the right thing.
