   Hi all,
   
    in the G1SurvRateGroup class there are three loops that use a `size_t` loop iteration variable that is compared to `uint`s in the condition, causing some implicit narrowing.
   
   Change the loop variables to also use `uints`.
   
   Pointed out by @kimbarrett during review of JDK-8349906.
   
   Testing: local compilation, github testing, checking other loop variables to match type
   
   Thanks,
     Thomas
