Original change's description:
> [wasm] Introduce jump table
> 
> This introduces the concept of a jump table for WebAssembly, which is
> used for every direct and indirect call to any WebAssembly function.
> For lazy compilation, it will initially contain code to call the
> WasmCompileLazy builtin, where it passes the function index to be
> called.
> For non-lazy-compilation, it will contain a jump to the actual code.
> The jump table allows to easily redirect functions for lazy
> compilation, tier-up, debugging and (in the future) code aging. After
> this CL, we will not need to patch existing code any more for any of
> these operations.
