    nr2.0: Fix test const_generics_3.rs
    
    gcc/testsuite/ChangeLog:
    
            * rust/compile/const_generics_3.rs: Modify test to run with name
            resolution 2.0 only and to handle the absence of a bogus
            resolution error.
            * rust/compile/nr2/exclude: Remove const_generics_3.rs.
    
    Signed-off-by: Owen Avery <powerboat9.gamer@gmail.com>
