    i386/testsuite: Fix scan tree dump in vect-epilogue-4.c
    
    vect-epilogue-4.c uses mask 64 byte to vectorize in epilogue part.
    Similar as r16-876 fix for vect-epilogue-5.c, we need to adjust the
    scan tree dump.
    
    gcc/testsuite/ChangeLog:
    
            * gcc.target/i386/vect-epilogues-4.c: Fix for epilogue
            vect tree dump.
