Qiuhao Li 7b339f287f fuzz: double the IOs to remove for every loop ... Instead of removing IO instructions one by one, we can try deleting multiple instructions at once. According to the locality of reference, we double the number of instructions to remove for the next round and recover it to one once we fail. This patch is usually significant for large input.
