There are other tests for fma on GFX11, though I'm not sure if they cover similar cases. Additionally, the hand written tests basically look for a single instruction. It seems a shame to reduce that clarity. It might be better to skip this patch. 
Or, alternatively, maybe file a ticket, add a TODO and let the test catch the changes in the output?
