From: Ian Romanick <ian.d.roman...@intel.com>
Commit b765119c changed the default value of all the counter bits to
64. However, older hardware only has 32 counter bits.
This has only been build-tested. We don't have any tests that verify
the advertised value against implementation behavior, so I don't know
what additional testing could be done.
NOTE: It appears that many Gallium drivers (at least r300 and i915g)
have the same problem, but I don't see a way for the state-tracker to
determine the counter size.
