Sanjay Patel 1fb7519cc1 [InstSimplify] fold splat of inserted constant to vector constant ... shuf (inselt ?, C, IndexC), undef, <IndexC, IndexC...> --> <C, C...> This is another missing shuffle fold pattern uncovered by the shuffle correctness fix from D70246. The problem was visible in the post-commit thread example, but we managed to overcome the limitation for that particular case with D71220. This is something like the inverse of the previous fix - there we didn't demand the inserted scalar, and here we are only demanding an inserted scalar.
