Changes the default value of `FuncSpecMaxIters` from 1 to 10. This allows specialization of recursive functions. To reduce the overhead of finding potential specializations we do slightly different things on following invocations of run() compared to the first one. In the first invocation we examine the entire module. We calculate the CodeMetrics for candidate functions and then examine all the interesting call sites. In later invocations we are only interested in call sites which reside in cloned functions created on the previous iteration.
