    [wasm] Implement toString of exported functions · 003f622a
    Clemens Backes authored
    We currently print asm.js functions converted to wasm as
    "function foo() { [native code] }", even though without asm to wasm
    translation we get the proper source code. This is an observable
    difference that should not be, and also foozzie finds this frequently in
    different variations.
    
    This CL makes us remember the start position (position of the "function"
    token) and end position (right behind the closing "}") of each function
    we transform to wasm. These offsets, together with the Script that
    contained the function, allows us to reconstruct the source code of the
    function for the {toString()} method.
