This PR implements the sign-extension operators that have been added to WebAssembly.
As noted here, the sign-extension operators proposal is a "finished proposal" - it has reached phase 4, and it is included in the latest draft of the specification.
And as noted here, sign-extension operators are already supported in Chrome, Firefox, Wasmtime, Wasmer, and Node.js (but not Safari).
