Historically, exploded graph dumps were disabled in non-debug builds. It was done so probably because a regular user should not dump the internal representation of the analyzer anyway and the dump methods might introduce unnecessary binary size overhead. It turns out some of the users actually want to dump this. Note that e.g. `LiveExpressionsDumper`, `LiveVariablesDumper`, `ControlDependencyTreeDumper` etc. worked previously, and they are unaffected by this change. However, `CFGViewer` and `CFGDumper` still won't work for a similar reason. AFAIK only these two won't work after this change.
