Add suffix parameter to DumpCFG

In a lot of cases it is practical to dump CFGs. However the current dumper
has a unique naming convention. By adding an optional suffix, we can dump
the same CompilationUnit before and after an optimization by using a different
suffix.

Also, by making it optional, the change is minimal.
