Use Response.url in DevTools

This tests that the DevTools utilize the Response.url property when using WebAssembly.instantiate to properly show the response-url.wasm file in the Sources / Debugger panel. The response-url.wasm file should show up next to the main.js and response-url.html files.

Steps

1. Open DevTools
2. Reload this page
3. Search for response-url.wasm in the Sources / Debugger panel
