Inserts a safepoint into transformed program.

At every loop head and at the entry of a function, CPS-transformed program will call the specified no-arg static public method that returns void. This is useful to pause the execution of un-cooperative CPS transformed programs.

A safepoint method can run some computation and return normally to keep the CPS interpreter going, or it can suspend the execution of a program.
