Original issue's description:
> [wasm] Indirect calls without function table cause validation errors.
>
> The spec defines that indirect calls in WebAssembly code should cause a
> validation error if no function table exists.
>
> The CL contains the following changes:
> 1) Throw a validation error for indirect calls if the function table
> not exist.
> 2) Do not create TF nodes to throw a runtime error for indirect calls
> if the function table does not exist.
> 3) Fix existing unit tests by creating a dummy function table.
> 4) Add new a new test which tests that indirect calls without function
> table cause a validation error.
