    [wasm] Implement memory.init and memory.drop · 4084185b
    Ben Smith authored
    `memory.init` copies bytes from a passive data segment to linear memory.
    
    `memory.drop` is an instruction that informs the wasm VM that the instance no
    longer needs access to the passive data segment.
    
    Information about the passive data segments, including their contents, length,
    and whether they are dropped, is stored in the `WasmInstanceObject` as primitive
    arrays.
