We currently can't legalize those, but we should really not be creating them in the first place, since legalization would probably look similar to the way we legalize CONCAT_VECTORS - basically replace the INSERT with a BUILD. This fixes PR311956. Differential Revision: https://reviews.llvm.org/D29961 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@295213 91177308-0d34-0410-b5e6-96231b3b80d8
