[PATCH] PR16182 - Visit parameter declaration of implicitly declared copy assignment operator.

[Richard Smith]

  It seems strange to me to build a TypeSourceInfo for a type that was not actually written. Maybe you could add an 'else' to TraverseFunctionHelper's

      if (TypeSourceInfo *TSI = D->getTypeSourceInfo())

  to visit the parameters of the function decl?
