5bdb13297f [wasm] merge js constants file in module-builder
We noticed that almost every call site were loading both files,
the split isn't necessary anymore.

In some message tests, removed the absolute line number to allow future
changes.

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.

49712d8acf [wasm] Call AsyncInstantiate directly when instantiating a module object
WebAssembly.instantiate is polymorphic, it can either take a module
object as parameter, or a buffer source which should be compiled first.
To share code between the two implementations, the module object was
first passed to a promise (i.e. which is the result of compilation).
However, passing the module object to a promise has a side effect if
the module object has a then function. To avoid this side effect I
remove this code sharing and call AsyncInstantiate directly in case
the parameter is a module object.
