[X86] Add DAG combine to remove sext i32->i64 from gather/scatter instructions.
Only do this pre-legalize in case we're using the sign extend to legalize for KNL.
This recovers all of the tests that changed when I stopped SelectionDAGBuilder from deleting sign extends.
There's more work that could be done here particularly to fix the i8->i64 test case that experienced split.
