radeon: Advertise correct GL_QUERY_COUNTER_BITS/GL_SAMPLES_PASSED value
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. Marek says, "For Gallium, a new PIPE_CAP or new get_xxx_param function will be needed."
