huoqingyi 9cf6e63579 Fix bugs in ts aot 
Description:
1.Fix the bug that Circuit IR args gates do not match the function args of the abc file.
2.Add class ArgumentAccessor to handle args gates of Circuit IR.
3.Modify to set the AOT function entry when constpool is being parsed.
4.For functions sharing the same instructions, add a map to collect duplicate infomation. The key of the map is the current method and the value is the first method with the same nstructions to be translated.
