<pre>Yes, with that, the float loop is unrolled and PSPom perf regression is fixed.
This:
SIMD16 shader: 156 instructions. 2 loops. 6802 cycles. 0:0 spills:fills.
Promoted 4 constants. Compacted 2496 to 1552 bytes (38%)
Changed to:
SIMD16 shader: 197 instructions. 1 loops. 5924 cycles. 0:0 spills:fills.
Promoted 17 constants. Compacted 3152 to 2176 bytes (31%)</pre>
