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).
