Added -f option to display output in folded format for conversion to flame graphs. This is a test example.

  # ./profile -f
    test-strlen-abc;__libc_start_main;main;a;b;strlen 34
    test-strlen-abc;__libc_start_main;main;a;b;strlen 28
    test-strlen-abc;__libc_start_main;main;a;b;strlen 15
    test-strlen-abc;__libc_start_main;main;a;b;strlen 12
    test-strlen-abc;__libc_start_main;main;a;b;strlen 11
    test-strlen-abc;__libc_start_main;main;a;b;strlen 9
