RFC (S) JDK-8050149: Experimental option to select the instruction sequence for x86 StoreLoad barrier

[Aleksey Shipilev]

Hi guys,

Any comments about pushing something like this into HS?
 https://bugs.openjdk.java.net/browse/JDK-8050149
 http://cr.openjdk.java.net/~shade/8050149/webrev.01/

This is a follow up for:
 https://bugs.openjdk.java.net/browse/JDK-8050147

I think the actual switch, if any, should happen in JDK-8050147, but I
would like to explore the alternatives here. Performance runs are
underway. Are there any other alternatives for StoreLoad missing?

Thanks,
-Aleksey.
