RFR (M) 8157726: VarHandles/Unsafe should support sub-word atomic ops [RESEND]

[stanislav lukyanov]

Hi Aleksey,

In 
http://cr.openjdk.java.net/~shade/8157726/webrev.jdk.03/src/java.base/share/classes/java/lang/invoke/MethodHandles.java.sdiff.html
"(non-numeric) atomic update" clause has been removed from 
arrayElementVarHandle's doc.
Is it by mistake, or am I missing something?

Thanks,
Stas
