      iris: Fix zeroing of transform feedback offsets in strange cases. · 6bd4cb92
      Kenneth Graunke authored
      Some of the dEQP.functional.transform_feedback tests end up doing
      the following sequence of operations:
      
         1. BeginTransformFeedback
         2. PauseTransformFeedback
         3. Draw
         4. ResumeTransformFeedback
      
      At step 1, we'd pack 3DSTATE_SO_BUFFER commands saying to zero the
      SO_WRITE_OFFSET registers.  At step 2, we disable streamout, so step 3
      doesn't bother emitting those commands.  Then, step 4 re-packs new
      3DSTATE_SO_BUFFER commands with offset = 0xFFFFFFFF, saying to continue
      appending at the existing offset.  This loads the value from the BO as
      the offsets - but we never actually zeroed it.
      
      So, just maintain a flag saying "we actually emitted the commands",
      and stomp offset back to zero until we emit some.
