RFR (XL): 8152664 - Support non-continuous CodeBlobs in HotSpot

[Rickard Bäckman]

Here is the updated webrev, rebased and I think I have fixed all the
comments with one exception.

I've avoided making CompiledMethodIterator and NMethodIterator a
template class for now. I agree we should do something to reuse the
parts that are identical but for now I think there will be a few more
changes to CompiledMethodIterator in an upcoming RFR. So can we hold off
with that change?

Thanks
