Summary:
- If a parameter is used, nonnull checking needs function prototype to
retrieve the corresponding parameter's attributes. However, at the
prototype substitution phase when a template is being instantiated,
expression may be created and checked without a fully specialized
prototype. Under such a scenario, skip nonnull checking on that
argument.
