Jim Grosbach 572868e146 ARM PKH shift ammount operand printing tweaks.
Move the shift operator and special value (32 encoded as 0 for PKHTB) handling
into the instruction printer. This cleans up a bit of the disassembler
special casing for these instructions, more easily handles not printing the
operand at all for "lsl #0" and prepares for correct asm parsing of these
operands.
