[Bug tree-optimization/26420] New: -ftree-vectorizer-verbose=1 prints unvectorized loops information

[rguenth at gcc dot gnu dot org]

tramp3d-v4.cpp:3740: note: vectorized 0 loops in function.

tramp3d-v4.cpp:3740: note: vectorized 0 loops in function.

tramp3d-v4.cpp:50941: note: vectorized 0 loops in function.

tramp3d-v4.cpp:3740: note: vectorized 0 loops in function.

tramp3d-v4.cpp:3740: note: vectorized 0 loops in function.

etc.

  if (vect_print_dump_info (REPORT_VECTORIZED_LOOPS))
    fprintf (vect_dump, "vectorized %u loops in function.\n",
             num_vectorized_loops);

here we should check if num_vectorized_loops is >0 or verbosity level
includes REPORT_UNVECTORIZED_LOOPS.  Though even in this case the
note does not provide any useful information.
