[Piglit] [PATCH 1/4] Add ConcurrentTestPool singleton.

[U. Artie Eoff]

The ConcurrentTestPool singleton will simplify the threading model
and remove the need to manage multiple ThreadPools.  Only one
threadpool is currently needed at this time and is meant to execute
cpu-only tests in separate threads.
