Generic zero-copy ArrayBuffer usage

Most APIs which accept binary data need to ensure that the data is not modified while they read from it. (Without loss of generality, let's only analyze ArrayBuffer instances for now.) Modifications can come about due to the API processing the data asynchronously, or due to the API processing the data on some other thread which runs in parallel to the main thread. (E.g., an OS API which reads from the provided ArrayBuffer and writes it to a file.)

On the web platform, APIs generally solve this by immediately making a copy of the incoming data. The code is essentially:

function someAPI(arrayBuffer) {
  arrayBuffer = arrayBuffer.slice(); // make a copy
