`MaxCond` is one of options. I guess it could be configurable just for theirs coding rules, since I think controlling `MaxCond` would not make sense.
I know we have to introduce other options as well. I will do later.
* `MaxCond`
* `MaxTVs` to restrict per-expression number of TVs
* "Max bytes of bitmap in the CU" to restict inter-function size of the bitmap.
