The test test/gc/survivorAlignment/TestPromotionFromSurvivorToTenuredAfterMinorGC.java on Solaris x64 and Windows x64 fails with 8u60b09 and 9.

The problem is that since JDK-8060025 the survivor alignment is used independently of target generation.

Tests to reproduce:

1. Take 8u60b09 or above
2. run jtreg -nr -va -vmoptions:' -XX:+UseG1GC ' hotspot/test/gc/survivorAlignment/TestPromotionFromSurvivorToTenuredAfterMinorGC.java
3. Observe error: Actual memory usage should not deviate from expected for more then 682456

E.g.
For 8u60b08 we could see:
Verifying memory usage in space: TENURED
Allocated objects count: 655360
Desired object size: 16
Actual object size: 16
Expected object size in space: 16
Expected memory usage: 13648120
Actual memory usage: 13735160
Memory usage diff: 87040
Max allowed usage diff: 682408

for 8u60b09 (and above):
Verifying memory usage in space: TENURED
Allocated objects count: 655360
Desired object size: 16
Actual object size: 16
Expected object size in space: 16
Expected memory usage: 13648984
Actual memory usage: 24141400
Memory usage diff: 10492416
Max allowed usage diff: 682456
STDERR:
java.lang.RuntimeException: Actual memory usage should not deviate from expected for more then 682456

alternatively, in jdk9 the test passes with a "Memory usage diff is incorrect, but it seems like someone else allocated objects" which is a false positive.

Regression: yes
Stable: yes
