Add aot binary analysis tool aot-analyzer, samples: ```bash # parse example.aot, and print basic information about AoT file $ ./aot-analyzer -i example.aot # parse example.aot, and print the size of text section of the AoT file $ ./aot-analyzer -t example.aot # compare these two files, and show the difference in function size between them $ ./aot-analyzer -c example.aot example.wasm ``` Signed-off-by: ganjing <ganjing@xiaomi.com>
