  -----------
  [VE] Change to promote i32 AND/OR/XOR operations

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.
