gfx90a does not have extended-image-insts but supports image/texture API's in 
HIP. Brian suggested to determine whether HIP image is supported based on 
whether the subtarget has image-insts.

I thought image-insts is a subtarget feature as it is defined in 
https://github.com/llvm/llvm-project/blob/main/llvm/lib/Target/AMDGPU/AMDGPU.td#L499

Did I miss something?
