clemensh 6572b5622e [wasm] Remove raw byte pointers from WasmModule ... These byte pointers (module_start and module_end) were only valid during decoding. During instantiation or execution, they can get invalidated by garbage collection. This CL removes them from the WasmModule struct, and introduces a new ModuleStorage struct as interface to the wasm wire bytes. Since the storage is often needed together with the ModuleEnv, a new ModuleStorageEnv struct holds both a ModuleEnv and a ModuleStorage. The pointers in the ModuleStorage should never escape the live range of this struct, as they might point into a SeqOneByteString or ArrayBuffer. Therefore, the WasmInterpreter needs to create its own copy of the whole module. Runtime functions that previously used the raw pointers in WasmModule (leading to memory errors) now have to use the SeqOneByteString in the WasmCompiledModule.
