Tamer Tas 25457c60a7 [testrunner] load tests concurrently into test execution processor 
loading every test up-front into the processing queue costs about 224MB for a
x64 testsuite run.

This CL eliminates that overhead by utilizing generators and threading.

LoadingProc now loads test after receiving the results of the loaded tests.
