Nathan Hjelm	aac611237b	opal/thread: clean up and add additional OPAL_THREAD macros ... This commit expands the OPAL_THREAD macros to include 32- and 64-bit atomic swap. Additionally, macro declararations have been updated to include both OPAL_THREAD_* and OPAL_ATOMIC_*. Before this commit the former was used with add and the later with cmpset.

Nathan Hjelm	a8c3699484	Fix performance regression caused by enabling opal thread support ... This commit adds opal_using_threads() protection around the atomic operation in OBJ_RETAIN/OBJ_RELEASE. This resolves the performance issues seen when running psm with MPI_THREAD_SINGLE. To avoid issues with header dependencies opal_using_threads() has been moved to a new header (thread_usage.h). The OPAL_THREAD_ADD* and OPAL_THREAD_CMPSET* macros have also been relocated to this header. This commit is cherry-picked off a fix that was submitted for the v1.8 release series but never applied to master. This fixes part of the problem reported by @nysal in #1902.
