Andreas Haas 441e6d4a3c [wasm] Do an additional IsWasmModuleObject check during instantiation 
When WebAssembly.instantiate or WebAssembly.instantiateStreaming is
called in JavaScript, internally we transfrom it into
WebAssembly.compile(buffer).then(WebAssembly.instantiate). However,
modifying the prototype of WebAssembly.Module can change the result of
WebAssembly.compile(buffer). With this CL we make sure that even if the
result of WebAssembly.compile is modified, there is still no type
confusion. In the long term we have to do a refactoring and remove
this internal transformation.
