Andreas Haas 6d08c94cb5 [wasm][debug] Provide WebAssembly Table entries to DevTools 
With this CL, V8 adds an internal field to the WebAssembly Table object
that is sent to DevTools to also show table entries. As WebAssembly
Tables get initialized lazily, V8 only shows the name of the function
instead of the function object itself.
