--- Comment #3 from Simon Pilgrim <llvm-dev at redking.me.uk> ---
Fixed in ToT at somepoint in the past 18 months - both with/without
-x86-experimental-vector-shuffle-lowering

    .globl    _v4i8
    .align    4, 0x90
_v4i8:                                  ## @v4i8
    .cfi_startproc
## BB#0:
    vmovd    (%rdi), %xmm0
    retq
    .cfi_endproc
