RFR: JDK-8151842: Local variables use have wrong names after JDK-8148736

[Bengt Rutisson]

Hi everyone,

Could I have a couple of reviews for this small change?

http://cr.openjdk.java.net/~brutisso/8151842/webrev.00/
https://bugs.openjdk.java.net/browse/JDK-8151842

With the fix for JDK-8148736 we changed from logging bytes to logging 
regions. However, two local variables still have "bytes" in their names:

eden_capacity_bytes_after_gc
survivor_capacity_bytes_after_gc

Thanks,
Bengt
