Kyle Lutz ec11d8cdc4 Add third-party perf tests 
This adds third-party performance tests to use in comparing
Boost.Compute with other parallel/GPGPU frameworks like Intel's
TBB and NVIDIA's Thrust along with the C++ STL.

Also refactors the timing and profiling infrastructure and adds
a simple perf.py driver script for running performance tests.

Kyle Lutz 3bc5bfaf78 Remove timer class 
This removes the timer class. The technique of measuring the time
difference between two different OpenCL markers on a command queue
is not portable to all OpenCL implementations (only works on NVIDIA).

A new internal timer class has been added which uses boost::chrono
(or std::chrono if BOOST_COMPUTE_TIMER_USE_STD_CHRONO is defined).
This new timer is used by the benchmarks to measure time elapsed
on the host.
