    testsuite: fix spaceship-narrowing1.C
    
    I made sure that Wnarrowing22.C works fine on ILP32, but apparently
    I didn't verify that spaceship-narrowing1.C works there as well.  :(
    
    gcc/testsuite/ChangeLog:
    
            * g++.dg/cpp2a/spaceship-narrowing1.C: Use __INT64_TYPE__.
