RFR: jsr166 jdk9 integration wave 7

[Peter Levart]

Hi,

I noticed that in ThreadLocalRandom and Striped64, Unsafe remains for 
the sole purpose of accessing 3 fields in java.lang.Thread class. Now 
that there are VarHandle(s), they could be combined with SharedSecrets 
to get rid of Unsafe access in those two classes. For example, in Striped64:

http://cr.openjdk.java.net/~plevart/misc/JavaLangThreadAccess/webrev.Striped64/

This has the added benefit that IDE(s) can search for usages of 
JavaLangThreadAccess.xxx methods to quickly find all the usages. Note 
that even though Thread is one of primordial classes, obtaining 
VarHandle(s) for its fields is lazy and works without problems...

Regards, Peter
