lib: add WebAssembly to primordials

[ExE-Boss]

This is used to handle support for WebAssembly modules and static analysis of named exports from CommonJS modules.

---

Note that adding WebAssembly types to /typings/primordials.d.ts depends on microsoft/TypeScript-DOM-lib-generator#959 in order to avoid adding lib: ["DOM"] to tsconfig.json.

Checklist

Failures in GitHub CI (e.g., test-esm-wasm) seem related?

[ExE-Boss]

I have no idea why:

const { WebAssemblyCompile } = primordials;
WebAssemblyCompile(...);

doesn’t work, but:

const { WebAssembly } = primordials;
WebAssembly.compile(...);

does.

FWIW, it works on my machine™, I do not get the same error as the CI (all the tests pass). I compile with the --node-builtin-modules-path configure flag, that might be related.

@ExE-Boss would you like to rebase? Maybe it will work with the current V8 version

[aduh95]

IIUC this is never going to work because of the --jitless flag:

node/deps/v8/src/flags/flag-definitions.h

Line 1533 in 38ef4e5

// --jitless also implies --no-expose-wasm, see InitializeOncePerProcessImpl.
