RFR(XS): JDK-8023643 - G1: assert failed when NewSize was specified greater than MaxNewSize

[Jesper Wilhelmsson]

Hi,

Can I have a review of this minor fix.

Since I was messing with that code anyway I fixed JDK-8023643 [1].

G1 didn't handle if the user sets incompatible NewSize and MaxNewSize. All other 
collectors exits with an error in this case, so I added the same check to the G1 
code path.

Thanks!
