This node was only used to detect recursion while inlining. We no longer
need to do this, because we disallow recursion in all programs.
The removal of one IRNode per inlined function actually allows for
slightly more aggressive inlining, since we restrict inlining based on
IRNode consumption. This allows the "ExponentialGrowth" tests to inline
a bit more deeply than before.
