RKSimon added a comment.
Would it be better to implement m_APInt_or_Undef and m_APFloat_or_Undef - explaining that the undef is only for vectors (and naturally must still contain at least one APInt).
Get that in with a couple of combines updated to use it (with thorough testing), We can then gradually audit the remaining cases.
