[11u] RFR: Backport of 8216041: [Event Request] - Deoptimization

[Yang Yi]

Hi,

Please can I request a review of this webrev for the backport of
https://bugs.openjdk.java.net/browse/JDK-8216041 ?

Webrev: http://cr.openjdk.java.net/~ddong/yiyang/11u-8216041/webrev.00/

This patch doesn't apply cleanly but is fairly trivial. The signature of 
method `Atomic::cmpxchg` and `register_static_type(jfrTypeManager.cpp)` is
not different comparing to upstream and jdk11u. Simply adjusting the 
argument position and adding extra parameters can solve this problem.

Best,Yang Yi
