Jim Grosbach 589130fac1 Simplify printing of ARM shifted immediates.
Print shifted immediate values directly rather than as a payload+shifter
value pair. This makes for more readable output assembly code, simplifies
the instruction printer, and is consistent with how Thumb immediates are
 displayed.
