This allows opt_algebraic to resolve open-coded
saturates into ir_unop_saturate before we potentially
mess it up by removing the min or max in min/max-pruning.
Since we are now emitting more free saturates on i965
this gives us some decrease in instructions.
total instructions in shared programs: 1317459 -> 1317065 (-0.03%)
instructions in affected programs: 4084 -> 3690 (-9.65%)
GAINED: 0
LOST: 0

Two purpose-written shaders are hurt by this.
They exercise the lack of saturate in the get_range
function in minmax_pruning.
This will get sorted out later in the series by
adding saturate to the get_range function.
