On the LLVM side (and also for the llvm-mc assembler), they distinguish 
all of the gfx* for the -mcpu= argument. See 
https://llvm.org/docs/AMDGPUUsage.html#id26 for that list.

Thus, I think it makes sense to do the same here.  The last column on 
that page lists the supported hardware but is it neither really up to 
date nor complete.

Thus, I found it easier to just mention gfx1100 as that's unique. On the 
ROCm side, AMD has:
