    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.
