## General improvements
* The control flow graph construction now takes simple Boolean conditions on local scope variables into account. For example, in `if (b) x = 0; if (b) x = 1;`, the control flow graph will reflect that taking the `true` (resp. `false`) branch in the first condition implies taking the same branch in the second condition. In effect, the first assignment to `x` will now be identified as being dead.

* Constant failing assertions, such as `Debug.Assert(false)`, are now taken into account. Syntactic successors of constant failing assertions are consequently dead code.
