Currently if you have an SMEM store followed by an SMEM load that loads the same location as was written, it won't work because the store isn't finished before the load is executed. This is NOT mitigated by an s_nop instruction on GFX10. Since we currently don't have proper alias analysis, this commit adds a workaround which will insert an s_waitcnt lgkmcnt(0) before each SSBO load if they follow a store. We should further refine this in the future when we can make sure to only add the wait when we load the same thing as has been stored.
