RFR (10,9,8): Cleanup shared code

[Roman Kennke]

I found some small/trivial diffs between Shenandoah's shared code and
upstream's shared code:

http://cr.openjdk.java.net/~rkennke/cleanup-shared/webrev.00/
<http://cr.openjdk.java.net/%7Erkennke/cleanup-shared/webrev.00/>

Ok to push?

Only a small trivial subset of this applies to shenandoah/jdk8u:
