RFR(XXS): 8222034: Thread-SMR functions should be updated to remove work around

[Daniel D. Daugherty]

Greetings,

I have a very small fix for the following bug:

     JDK-8222034 Thread-SMR functions should be updated to remove work 
around
     https://bugs.openjdk.java.net/browse/JDK-8222034

Webrev URL: http://cr.openjdk.java.net/~dcubed/8222034-webrev/0_for_jdk13/

I would like to hear from Erik Osterlund and Martin Doerr on this review.
Of course, anyone else is also welcome to chime in.

This fix has been tested with a Mach5 tier[1-3] run.

Thanks, in advance, for any questions, comments or suggestions.

Dan
