RFR: 8134626 - Misc cleanups after generation array removal

[David Lindholm]

Jesper,

I think these changes looks good. There are changes to quite a lot of 
files, especially in increment 2. I don't know if backporting fixes 
later on will be a problem? Also, some of these files are in runtime, 
for example vmStructs.cpp. Maybe you should let someone from runtime 
review as well?

That said, I think these are nice cleanups.


Thanks,
David
