radv: disable the auto-waitcnt-before-barrier LLVM option
This option allows us to remove additional s_waitcnt instructions because s_barrier internally does s_waitcnt 0. Though, apparently there is a problem with LDS accesses that causes rendering issues with FFXV and DXVK. Disable this optimization for now (RadeonSI still uses it).
