[PATCH] D8149: Add hasUnderlyingType narrowing matcher for TypedefDecls, functionProtoType matcher for FunctionProtoType nodes, extend parameterCountIs to FunctionProtoType nodes

[Richard via cfe-commits]

LegalizeAdulthood added a comment.

Is there any reason we can't proceed with the patch as-is and then see if it can be refactored into an overload of `hasType`?
