  1. Detect and diagnose infinitely-recursive code 

    Add a new warning that detects when a function will call itself
recursively on all code paths.  Attempts to invoke functions like this
may cause unbounded stack growth at least or undefined behavior in the
worst cases.

The detection code is implemented as DFS for a reachable exit path in
a given SILFunction.
