> Hi all,
> 
> This patch fixes several `int` overflows relating to flat array element 
> loads/stores. 
> I've included some gtests that address a subset of these changes.  We should 
> test flat arrays larger than 16GB in size, which is not something we can 
> feasibly do in our tier1 jtreg tests. I've filed 
> [JDK-8372261](https://bugs.openjdk.org/browse/JDK-8372261) as a follow-up RFE 
> to investigate this.
> 
> Testing: tiers 1-4, 
> [`LocalityCheck.java`](https://bugs.openjdk.org/secure/attachment/117136/LocalityCheck.java)
>  run locally 100 times.
