CRR (S): 7113012: G1: rename not-fully-young GCs as "mixed"

[Bengt Rutisson]

Hi Tony,

Sorry for the late review. I looks good to me.

One minor thing:

g1CollectorPolicy.hpp:
Several lines in the range 373-432 (new version) has indentation that 
looks strange to me. For example line 375 here:

  373   size_t predict_young_card_num(size_t rs_length) {
  374     return (size_t) ((double) rs_length *
  375                                         
predict_young_cards_per_entry_ratio());
  376   }

Other than that - Ship it!

Bengt
