BUILD_CONST_KEY_MAP can be optimized based on #41835 optimization. 1. compiler checks keys tuple is distinct. 2. Add distinct flag to BUILD_CONST_KEY_MAP oparg To be considered: * Should we use new opcode, instead of flag in oparg? * Is this technique safe? Wrong co_consts can make invalid dict instance.
