glsl: Rebalance expression trees that are reduction operations.
The intention of this pass was to give us better instruction scheduling opportunities, but it unexpectedly reduced some instruction counts as well: total instructions in shared programs: 1666639 -> 1666073 (-0.03%) instructions in affected programs: 54612 -> 54046 (-1.04%) (and trades 4 SIMD16 programs in SS3)
