radeonsi: Use buffer loads and stores for passing data from TCS to TES.
We always try to use 4-component loads, as LLVM does not combine loads and they bypass the L1 cache. We can't use a similar strategy for stores and this is especially notable with the tess factors, as they are often set with separate MOV's per component in the TGSI. We keep storing to LDS and the LDS space, so we can load the outputs later, either due to the shader, of for wrting the tess factors.
