    c++: Improve redeclared parameter name diagnostic [PR94588]

    While reviewing [basic.scope.param] I noticed we don't show the location
    of the previous declaration when giving an error about "A parameter name
    shall not be redeclared in the outermost block of the function definition".

            * name-lookup.c (check_local_shadow): Add an inform call.

            * g++.dg/diagnostic/redeclaration-1.C: Add dg-message.
