[LLVM] DIRT 3 horrible performance when Shadows set to very high

Once you set Shadows to very high in the Options Menu the game slows down. You have to use DXVK to run the game, version doesnt matter.
I already reported this last year when I was still using my Radeon HD 7970: https://github.com/doitsujin/dxvk/issues/67#issuecomment-421925690
The game takes a nose dive from 134 to 29 fps once you switch the settings.
I tried today with my new Vega 56 and ACO: with LLVM: 72,5 fps with ACO: 206,3 fps
So we finally have the proof that LLVM is causing this. This might be the same problem we have with the long standing and still valid bug: https://bugs.freedesktop.org/show_bug.cgi?id=100069
