2015-06-25[Concepts] Parsing of requires-clause in template-declarationHubert Tong1-0/+29
Summary: This change implements parse-only acceptance of the optional requires-clause in a template-declaration. Diagnostic testing is added for cases where the grammar is ambiguous with the expectation that the longest token sequence which matches the syntax of a constraint-expression is consumed without backtracking.
