In the inner loop of the SIMD version of the mandelbrot program [here](https://github.com/lars-t-hansen/simd-bench) the only really ugly bit is the code generated for any_true, for exactly the reason outlined in comment 0. The code there is additionally a negated test, `(i32.eqz (i32x4.any_true ...))` and we need to handle that and its variations too.
