ARM Thumb2 asm syntax optional destination operand for binary operators.

When the destination operand is the same as the first source register
operand for arithmetic instructions, the destination operand may be omitted.

For example, the following two instructions are equivalent:
and r1, #ff
and r1, r1, #ff
