  -----------
  [MemCpyOpt] Handle scalable aggregate types in memmove/memset formation (#80487)

Without this change, the included test cases crash the compiler. I
believe this is fallout from the homogenous scalable struct work from a
while back; I think we just forgot to update this case.

Likely to fix https://github.com/llvm/llvm-project/issues/80463.
