  [AMDGPU][GlobalISel] Fix selection of image sample g16 instructions

Pre-GFX10 A16 modifier would imply G16. From GFX10 and onwards there are
separate instructions for 16bit gradients. This fixes the condition for
selecting G16 opcodes. Also stop adding G16 flag to instructions that do not
use gradients for GFX10 onwards.
