[PATCH] D92553: [ARM][X86] Match dual lane vmovs from insert_vector_elt

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added a comment.

Much of the ISD::BUILD_VECTOR creation code tries to use this and relies on sorted insertions chains - would it be better just to add a TLI virtual method that disables this at the target level for specific valuetypes?
