[Mesa-dev] [PATCH 3/3] radeon/llvm: Use alloca instructions for larger arrays

We were storing arrays in vectors, which was leading to some really bad spill code for large arrays. allocas instructions are a better fit for arrays and LLVM optimizations are more geared toward dealing with allocas instead of vectors. For arrays that have 16 or less 32-bit elements, we will
