[Mesa-dev] [PATCH v3 0/2] r600: Fix array texture slice index evaluation

it turned out that the failures with GATHER*O were the result of a faulty
optimization done by sb. So for consistensy I'll also add the offset for 
GATHER4_O and GATHER4_C_O in the SET_TEXTURE_OFFSET call which alleviates the
problems with sb.

Apart from that I've just fixed some comments following Roland's remarks. 

I ran the dEQP GLES 2, 3, and 31 suites and  
   piglit run gpu -t texture -t gather 

I didn't see any regressions, but
   textureSize 140 tes sampler2DArrayShadow -auto -fbo
seems to be unstable. It usually passes, but once in a while it fails (on both, 
master and with this patch applied)

  r600: set rounding mode for texture array layer selection
