RFR: 8286189 G1: Change "wasted" memory to "unused" memory in reporting [v2]

[Thomas Schatzl]

> Hi all,
> 
>   please review this change of the term "wasted" to "unused" in memory reporting; "wasted" is a bit ambiguous, meaning memory that can't be used because it's blocked by something external (like the space at the end of humongous regions where gc needs to wait until the humongous objects is freed by the application).
