--- Comment #1 from Simon Pilgrim <llvm-dev at redking.me.uk> ---
rL363582 - [X86][AVX] Split under-aligned vector nt-stores.
rL363592 - [X86][SSE] Scalarize under-aligned XMM vector nt-stores (PR42026)

Resolving - we already have the allowsMisalignedMemoryAccesses mechanism to
generically split load/stores, targets can override this to improve codegen
where necessary.
