RFR: 8027643 - Merge GenCollectorPolicy and TwoGenerationCollectorPolicy

[Stefan Johansson]

Hi Jesper,

The change looks good.

Do the further cleanups you mention include getting rid of the 
_generations array in GenCollectorPolicy and instead having a 
GenerationSpec for young and one for old? If not, I think that is 
something that should be added in upcoming one, since the policy no 
longer supports anything but 2 generations.

Cheers,
Stefan
