Compiling LLVM in release mode, and the out-of-tree project in debug mode, is a very common approach to reduce compilation times. In general, looking beyond LLVM, a debug build of the software stack should not be needed to build your own downstream software.

That's why I'm not sure. On one hand I do agree that it makes life of the downstream project easier, on another I was hearing 
 "downstream's problem is downstream's problem", as when you include header file as if debug is enabled, it's rightful to expect proper symbols are defined.
