AMDGPU: Mark s_barrier as a high latency instruction These were marked as WriteSALU, which is low latency. I'm guessing at the value to use, but it should probably be considered the highest latency instruction. I'm not sure this has any actual effect since hasSideEffects probably is preventing any moving of these. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@247060 91177308-0d34-0410-b5e6-96231b3b80d8
