radv: add a workaround for Monster Hunter World and LLVM 7&8
The load/store optimizer pass doesn't handle WaW hazards correctly
and this is the root cause of the reflection issue with Monster
Hunter World. AFAIK, it's the only game that are affected by this
issue.
This is fixed with LLVM r361008, but we need a workaround for older
LLVM versions unfortunately.
