I think the patch merely exposes another existing bug.

But first things first - is the message fatal?

I think the problem was "introduced" with
7372e3cf5f2df9dd2ec0423a4425baad098bf326 in order to workaround a LLVM
bug.
While later mesa commit 18b12bf53351e1a902dc1f2e527a94ec8d8f3eff aimed
to silence the message.

Can someone check which LLVM version has the the original issue
resolved so we call LLVMParseCommandLineOptions() only as needed.

Thanks
Emil
