Thanks Richi's comments.
I have sent a new patch with addressing your comments.

I am so sorry V2 patch just broke on boostrap.
I sent the V3 patch that fixed it.

Thanks.

Can you instead swap both checks and do an else if for the mask case?
If we ever record both len and mask we will fail the vectorization
anyway.

I think you want build_all_ones_cst (masktype), using '1' looks wrong
at least.  The alternative is constant_boolean_node (true, masktype).

I've seen the later refactoring patch but it seems garbled white-space
wise (this is also a case where context diffs would make review easier).
 
As said I'd like to see
 
        if (loop_lens)
          ... produce 'len' argument ...
 
        if ((loop_lens || final_mask)
            && use-len-mask)
          ..
        else if (loop_lens && use-len)
          ..
        else if (final_mask && use-mask)
          ..
 
maybe it is that, but it's hard to identify :/  It would be nice
to do the optab queries only once and compute a
partial_or_mask_vector_ifn in the analysis phase when we register 
lens/masks
so we don't have to re-do that.  Like the
 
+                           if (targetm.vectorize.get_mask_mode 
(vmode).exists (
+                                 &maskmode)
+                               && can_vec_mask_load_store_p (vmode, 
maskmode,
+                                                             false))
 
stuff.  If we arrive here we know we can code-generate with lengths
if loop_lens and with masks when final_mask (and with both when both).
What we don't easily know is whether we have to use
LEN_MASK_LOAD when just 'final_mask' or just 'loop_lens' and that's
something we should know as well in a more easy way.  With a
partial_or_mask_vector_ifn we could just switch () on that.
 
That said, your patch seems to at least commpute the len only once
(this original patch, not the unreadable "refactoring").
