In preparation to optimize cyclic-redundancy-check loops using table-lookup using the newly introduced HashRecognize analysis, add tests with CRC loops (which will get optimized), and check the result against a Sarwate table-lookup (which will not get optimized). The companion change is llvm/llvm-project#143208.
