 <p>Generates an IR compute function that calls the appropriate interpreted Get*Val() compute function. This is useful for builtins that can't be implemented with the UDF interface (e.g. functions that need short-circuiting) and that don't have custom codegen functions that use the IRBuilder. It doesn't provide any performance benefit over the interpreted path. TODO: this should be replaced with fancier xcompiling infrastructure </p>
