getPointerToNamedFunction - This method returns the address of the specified function by using the MemoryManager. As such it is only useful for resolving library symbols, not code generated symbols.

If AbortOnFailure is false and no function with the given name is found, this function silently returns a null pointer. Otherwise, it prints a message to stderr and aborts.

recompileAndRelinkFunction - This method is used to force a function which has already been compiled, to be compiled again, possibly after it has been modified.
