Original Commit Message:

    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.
