VE has only 64 bits AND/OR/XOR instructions. We pretended that VE has 32 bits instructions also, but doing it increase the number of generated instructions. Therefore, we decide to promote 32 bits operations and use only 64 bits instructions in back end. We also avoid pretending that VE has 32 bits LEA instruction. Update regression tests also.
