    ranger-op: Use CFN_ constant instead of plain BUILTIN_ one
    
    when compiling gimple-range-op.cc, clang issues warning:
    
      gimple-range-op.cc:1419:18: warning: comparison of different enumeration types in switch statement ('combined_fn' and 'built_in_function') [-Wenum-compare-switch]
    
    which I hope is harmless, but all other switch cases use CFN_ prefixed
    constants, so I guess the ISINF case should too.
    
    gcc/ChangeLog:

            * gimple-range-op.cc
            (gimple_range_op_handler::maybe_builtin_call): Use
            CFN_BUILT_IN_ISINF instead of BUILT_IN_ISINF.
