; During legalization, the vselect mask is 'type legalized' into a
; wider BUILD_VECTOR. This causes the introduction of a new
; sign_extend_inreg in the DAG.
;
; A sign_extend_inreg of a vector of ConstantSDNode or undef can be
; always folded into a simple build_vector.
;
; Make sure that the sign_extend_inreg is simplified and that we
; don't generate psll, psraw and pblendvb from the vselect.
