Prior to this commit, private non-primitive relax functions would be discarded by `FuseTIR`. If any calls to these functions exist, the resulting `IRModule` would be ill-formed. This commit updates `FuseTIR` so that it only applies updates to functions with `attr::kPrimitive`, and calls into those functions. To retain backwards compatibility, `DeadCodeElimination` is applied as a post-processing step.
