hi, @paulwalker-arm

  I find that without this refactor patch, the MVT::nxv2i32 type is also lega default, so the 'and' insn can be deleted in tryToFoldExtOfMaskedLoad.
  
  then, if we set it expand, the condition !TLI.isLoadExtLegalOrCustom(ExtLoadType, VT, Ld->getValueType(0)) in above function tryToFoldExtOfMaskedLoad will prevent it from optimizing.
