i965: Add support for xfb overflow query on conditional render.
Enable the use of a transform feedback overflow query with glBeginConditionalRender. The render commands will only execute if the query is true (i.e. if there was an overflow). Use ARB_conditional_render_inverted to change this behavior. v4: - reuse MI_MATH calcs from hsw_queryob (Kenneth) - fallback to software conditional rendering when MI_MATH is not available (Kenneth) v5: - check query->Target (Kenneth) Signed-off-by: Rafael Antognolli <[email protected]> Reviewed-by: Kenneth Graunke <[email protected]>
