--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Can you try to bisect to an affected source file (just use -fno-tree-vectorize
on all but one) and there to whether it is basic-block or loop vectorization
(-fno-tree-loop-vectorize / -fno-tree-slp-vectorize) and specific
loop/basic-block with -fdbg-cnt=vect_slp:N or -fdbg-cnt=vect_loop:N?

Note that it seems that tonto also fails (since forever) with AVX2 on x86_64.
