results in heavy gains, the specialized function is kept,
otherwise the original function is used instead.
FunctionHoister and ExpressionSplitter are recommended as prerequisites since they make the step
more efficient, but are not required for correctness.
In particular, function calls with other function calls as arguments are not inlined, but running
ExpressionSplitter beforehand ensures that there are no such calls in the input.
