<pre>Right now we can check if an instruction supports the zero-idiom with:
```
echo 'vxorps %ymm0, %ymm0, %y^C| ./bin/llvm-exegesis -mode=uops
-snippets-file=-
```
It would be nice if the llvm-exegesis SnippetGenerator could generate
configurations for all MCInstPredicates in the SchedModel to discover which
instructions support the zero idiom.</pre>
