ARM SSAT instruction 5-bit immediate handling.
The immediate is in the range 1-32, but is encoded as 0-31 in a 5-bit bitfield.
Update the representation such that we store the operand as 0-31, allowing us
to remove the encoder method and the special case handling in the disassembler.
Update the assembly parser and the instruction printer accordingly.
