Nit: the `OutContext.getOrCreateSymbol(FuncName + Suffix)`  bit seems like it might be worth factoring out to keep the case arms focused

```
auto GOCS = [this](StringRef Suffix) {
  return OutContext.getOrCreateSymbol(FuncName + Suffix);
};
switch (RIK) {
case RIK_NumAGPR: return GOCS(".num_agpr");
case RIK_NumSGPR: return GOCS(".num_sgpr");
// ...
}
```
