When running The Witcher 3 through DXVK there is terrain corruption in specific
areas. This only occurs when radv is build against LLVM8-svn (r348050).
I tested the following configurations:

- Mesa 18.2.5 + LLVM 7 -> renders correctly
- Mesa-git b186731d5e413c + LLVM7 -> renders correctly
- Mesa-git b186731d5e413c + LLVM8 r348050 -> corrupted

My gpu is an RX580. I'll also attach a screenshot, savegame and renderdoc
capture of the problematic area.
