I believe that the previous approach was essentially off-the-cuff, done
whichever way was most convenient.
If someone were to implement the same functionality for other architectures as
well, they would find three pieces of code with very poor style.
To leave behind code that is more ergonomic for future developers, at the very
least, the logic for handling features should be separated and handled
individually.
```c++
auto handleArch = [&](StringRef Feature) { ... }
auto handleTune = [&](StringRef Feature) { ... }
if(feature.startwith("arch=") handleArch(feature)
else (feature.startwith("tune=") handleTune(feature)
else if ( ... ) ...
else {
}
```
