AMDGPU: Don't use SDNodeXForm for DS offset output

Browse Source 
The xform has no real valuewhen it's using out of a complex pattern
output. The complex pattern was already creating TargetConstants with
i16, so this was just unnecessary machinery.

This allows global isel to import the simple cases once the complex
pattern is implemented.
