    selftests: Disable range test on capabilities
    
    This disables a selftest that tries to invert a range where the domain
    is a capability type, as this is currently unsupported (and leads to an
    ICE).
    
    gcc/ChangeLog:
    
            * range-op.cc (range_tests): Don't try and invert a range if the
            domain is a capability type.
