RFR: 8189276: Make SuspendibleThreadSet and related code available to other GCs

[Zhengyu Gu]

Hi Roman,

This looks much better.

Please fix this:

src/hotspot/share/gc/shared/suspendibleThreadSet.hpp

25 #ifndef SHARE_GC_COMMON_SUSPENDIBLETHREADSET_HPP
26 #define SHARE_GC_COMMON_SUSPENDIBLETHREADSET_HPP


Thanks,

-Zhengyu
