This would be simpler with a `toDescriptorRangeType()` helper (whether as a static function or even just a lambda). Also, the flags argument to `verifyDescriptorRangeFlag` looks like it's just immediately cast back to a dxbc::DescriptorRangeFlags - we should just update the signature to take the enum in the first place.
```c++
      if (!llvm::hlsl::rootsig::verifyDescriptorRangeFlag(
              Version, toDescriptorRangeType(Clause->Type), Clause->Flags))
        ReportFlagError(Loc);
```
