Summary: `SizeClassForTransferBatch` is expensive and is called for every `CreateBatch` and `DestroyBatch`. Caching it means `kNumClasses` calls in `InitCache` instead. This should be a performance gain if more than `kNumClasses / 2` batches are created and destroyed during the lifetime of the local cache. I have chosen to fully remove the function and putting the code in `InitCache`, which is a debatable choice. In single threaded benchmarks leveraging primary backed allocations, this turns out to be a sizeable gain in performances (greater than 5%). In multithreaded benchmarks leveraging everything, it is less significant but still an improvement (about 1%).
