<pre>The following image atomic instructions are legal and may be assembled by sp3
w/o any issues:
image_atomic_add v[5:6], v252, s[8:15] dmask:0x1 tfe
image_atomic_add v[5:7], v252, s[8:15] dmask:0x3 tfe
image_atomic_cmpswap v[5:7], v252, s[8:15] dmask:0x3 tfe
image_atomic_cmpswap v[5:9], v252, s[8:15] dmask:0xf tfe
However only the first one may be assembled by llvm assembler and only for
GFX7-GFX9. For GFX10 all of these fail to assemble.</pre>
