IPC was failing due to calling fork when HSA was open. The fix
was correcting incomplete cleanup in several other tests.
TestBase::Close (via CommonCleanUp) now checks that HSA is properly
closed between tests.
rocrtstPerf.Memory_Async_Copy uses hwloc which uses OpenCL which
has no shutdown routine. Consequently this test can not cleanup
properly. I added a hack to force HSA refcount to the value
it should have if OpenCL were cleaning up but this leaks resources
and potentially puts hwloc & OpenCL in a bad state.
OpenCL loads LLVM which installs some exit handlers. Those handlers
can't execute in a child process and can't be removed since OpenCL
doesn't cleanup. IPC hacks around this by aborting rather than exiting
in the child process.
