    ranger: Fix `-Werror' build error with `ranger_cache::push_poor_value'
    
    Remove a commit 86534c07a390 ("Disable poor value processing in ranger
    cache.") regression that caused GCC not to build anymore if `-Werror'
    has been enabled:
    
    .../gcc/gimple-range-cache.cc: In member function 'bool ranger_cache::push_poor_value(basic_block, tree)':
    .../gcc/gimple-range-cache.cc:850:44: error: unused parameter 'bb' [-Werror=unused-parameter]
      850 | ranger_cache::push_poor_value (basic_block bb, tree name)
          |                                ~~~~~~~~~~~~^~
    .../gcc/gimple-range-cache.cc:850:53: error: unused parameter 'name' [-Werror=unused-parameter]
      850 | ranger_cache::push_poor_value (basic_block bb, tree name)
          |                                                ~~~~~^~~~
    
    To keep the change to the minimum mark the parameters reported unused.
    
            gcc/
            * gimple-range-cache.cc (ranger_cache::push_poor_value): Mark
            parameters unused.
