Sorry, I was unclear. That's the entire program with a huge number of slp
opportunities. Each iteration in the program is ~40k instructions. It's not
directly related to the test case, which is artificial, and arose from me
exploring the differences between gcc and clang code generation.

It does demonstrate that clang's slp is counterproductive. I promise to repeat
the experiment with gcc once it stops ICEing.
