wasm_config_set_segue_flags(wasm_config_t *config, uint32 segue_flags);
```

* Enable using GS register as the base address of linear memory in linux x86_64,
* which may speedup the linear memory access for LLVM AOT/JIT:
* bit0 to bit4 denotes i32.load, i64.load, f32.load, f64.load, v128.load
* bit8 to bit12 denotes i32.store, i64.store, f32.store, f64.store, v128.store
* For example, 0x01 enables i32.load, 0x0100 enables i32.store.
* To enable all load/store operations, use 0x1F1F
