Typically names longer than -non-global-value-max-name-size will just get renamed if there is a collision after truncating. This is fine since we typically don't reference Values by name. However LLParser does reference Values by name, so report an error when that happens, otherwise weird issues can crop up if there are name collisions (e.g. verifier issues with the changed test case because we end up reusing the same block for `testz` and `testa`).
