The standard says: The optional requires-clause ([temp.pre]) in an init-declarator or member-declarator shall be present only if the declarator declares a templated function ([dcl.fct]). This implements that limitation, and updates the tests to the best of my ability to capture the intent of the original checks. Differential Revision: https://reviews.llvm.org/D125711
