Anton Afanasyev 6a5f49a1ac [AggressiveInstCombine] Add `{insert/extract}element` to `TruncInstCombine` DAG 
Alive2 for `{insert/extract}element`: https://alive2.llvm.org/ce/z/hwy_E-

Actually, no one file of test suite is touched by this change,
which means that is rare pattern not generated by frontend. But
it's worth being in place.
