There's no official extension.
Will go with dxo.

```
const auto &TC = static_cast<const toolchains::HLSLToolChain *>(
getToolChain(Args, C.getDefaultToolChain().getTriple()));
```
will hit " no viable conversion from 'const clang::driver::ToolChain' to 'const
toolchains::HLSLToolChain'"
```
const auto &TC = getToolChain(Args, C.getDefaultToolChain().getTriple());
const auto *HLSLTC = static_cast<const toolchains::HLSLToolChain *>(&TC);
```
works, is it OK?
