--- Comment #2 from Sanjay Patel <spatel+llvm at rotateright.com> ---

So we won't replace 2 scalar constant stores with 1 vector constant load + 1
vector store (and there's a corner case test for where it would likely have
been a win), but we should get cases where we know the vector ops reduce
instruction count.
