I assume tooling (like LLDB) benefitted from the fact that we pretended HIP is C++ (like we do for rust e.g.,). Would this break those use-cases?

I have updated the description with some motivation. I can look into providing an update for lldb to assume C++ when it sees DW_LANG_HIP. (A user can also set the language as well). Should that be included in this PR?
