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.

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).

This ports radv to the shared code, however due to a bug in LLVM
version prior to 7, radv cannot add target info at this stage,
as it would leak one for every shader compile, however I'd prefer
to keep this llvm damage in the shared code, since it isn't the
driver at fault here. We just add a flag to denote if the driver
can support leaking the target info or not, and the common code
does the right thing depending on the llvm version.

We want to share this code with radv in the future, so port
it out of radeonsi.
Add a return value as radv will want that to know if this

Since radv uses compute rings and we can't know when we are setting
up the shaders what ring they are to be used on, we should just use
the default xnack setting. This may be suboptimal in some places,
but if we hit a problem, we likely should try and address this
between llvm and mesa.
