    testsuite: Fix part of sve-sizeless-2.c
    
    r15-5783-gb5df3eefd70064 missed to update part of sve-sizeless-2.C to
    include the declaration of the bar function.
    This corrects the oversight there.
    
    Pushed as obvious after testing the tecase for aarch64-linux-gnu.
    
    gcc/testsuite/ChangeLog:
    
            * g++.dg/ext/sve-sizeless-2.C: Add declaration of bar.
