--- Comment #31 from Simon Pilgrim <llvm-dev at redking.me.uk> ---
Resolving, this was fixed by Craig at rL314914 - the MOVSS/MOVSD instructions
now take VR128 regclass as input so the conversion/commutation to BLENDPS no
longer requires a COPY. So there is no need for the late insertion into the LIS
maps in this particular case.

If we can reduce any of the test cases it'd still be useful to add them to
