    d: Remove setting of target-specific global.params flags from front-end
    
    Now that all dependencies on these flags have been removed, there's no
    need to test and set them.
    
    gcc/d/ChangeLog:
    
            * d-builtins.cc (d_add_builtin_version): Remove all setting of
            target-specific global.params.
            * typeinfo.cc (create_typeinfo): Don't add argType fields to
            TypeInfo_Struct.
