Comment:
Completed this change. We no longer use Note, rather use
{{{
case tick<mod,n> of
_ -> ...
}}}
The generated code is the same boolean-wise as the old tick method.
* In some cases we generate better CAFs.
* The execution runtime is faster with -O2. (~50% faster on raytracer)
* The compile time is slower with -O2. (~50% slower, perhaps because of
new optimizations kicking in)
