        <pre>With NIR we end up with :

        loop {
                block block_1:
                /* preds: block_0 block_5 block_7 */
                vec1 32 ssa_8 = phi block_0: ssa_3, block_5: ssa_4, block_7:
ssa_19
                vec1 32 ssa_9 = phi block_0: ssa_2, block_5: ssa_17, block_7:

                vec1 32 ssa_10 = phi block_0: ssa_1, block_5: ssa_4, block_7:

                vec1 32 ssa_14 = ige ssa_12, ssa_5
                /* succs: block_2 block_3 */
                if ssa_14 {
                        block block_2:
                        /* preds: block_1 */
                        break
                        /* succs: block_8 */
                } else {

                        /* preds: block_1 */
                        /* succs: block_4 */
                }
                block block_4:
                /* preds: block_3 */
                vec1 32 ssa_15 = ilt ssa_6, ssa_12
                /* succs: block_5 block_6 */
                if ssa_15 {
                        block block_5:
                        /* preds: block_4 */
                        vec1 32 ssa_16 = iadd ssa_12, ssa_7
                        vec1 32 ssa_17 = load_const (0x3f800000 /* 1.000000 */)
                        continue
                        /* succs: block_1 */
                } else {
                        block block_6:
                        /* preds: block_4 */
                        /* succs: block_7 */
                }
                block block_7:
                /* preds: block_6 */
                vec1 32 ssa_18 = iadd ssa_12, ssa_7
                vec1 32 ssa_19 = load_const (0x3f800000 /* 1.000000 */)
                /* succs: block_1 */
        }

So all we need to do is move everything after the if into the else block and
remove the continue. Removing myself as assignee, this would probably be a good
beginners task.</pre>
