> Some DirectCodeBuilder related optimizations to improve startup and running > performance: > 1. Merge calls, merge writeU1 and writeU2 into writeU3 > 2. Merge calls, merge writeU1 and writeIndex operations > 3. Directly use writeU1 instead of writeBytecode > 4. Rewrite the implementation of load and store
