This also moves some common code from jit_optimizer.cc and aot_optimizer.cc to a new common file, optimizer.cc. The code is almost unchanged from the aot_optimizer.cc version, apart from the calls to PurgeNegativeTestCidsEntries. A flag emulates the behaviour of the simpler jit_optimizer.cc version. Benchmark tests are running to see which is better.
