The WebAssembly specification requires the "name" property of (exported)
function wrappers to hold the index of the function within the module,
and the default ToString algorithm for Function instances thus generates
something along the lines of `function 42() { [native code] }`, which is
technically correct, but not very useful to developers to diagnose
(humans don't think of functions in a module in terms of their indices).
With this CL, we change the description returned for Wasm (exported)
functions to use the debug name of the Wasm function instead.
