This is an early hacked version of mesa that uses the register:
http://cgit.freedesktop.org/~jljusten/mesa/log/?h=cs%2bps

I veried reading the register with the modified mesa and a piglit
test. I first tested with the cmd parser disabled, and then with this
patch.

I'm waiting for the initial GL_ARB_pipeline_statistics_query extension
(without CS support) to make it upstream in mesa before finishing and
sending out the CS support.

If this is in next, can I proceed to upstream a mesa patch that
depends on version 3 of the command parser? Or, should I wait until
this makes it fully upstream?
