Breaking Changes

Remove the LLVM MCJIT mode, replace it with LLVM ORC JIT eager mode Add option to pass user data to the allocator functions of RuntimeInitArgs Change how iwasm returns:

• return 1 if an exception was thrown, else
• return the wasi exit code if the wasm app is a wasi app, else
• keep the same behavior as before

Enable bulk memory by default

New Features

Add control for the native stack check with hardware trap Add memory watchpoint support to debugger Add wasm_module_obtain() to clone wasm_module_t Implement Fast JIT dump call stack and perf profiling esp-idf: Add socket support for esp-idf platform
