RFR 8155674: Move javac towards a "by-file" compilation policy

[Maurizio Cimadamore]

Also don't forget that the cycle problem is temporary  - as discussed in 
that thread, the fix here is to actually get rid of erasure (which is 
something we did already in an experimental patch in Valhalla) which 
then removes the ordering problems with supertypes/subtypes. We plan to 
do further experiments with this in the Valhalla repo and move this code 
to 10 when ready.
