Defining custom Module.instantiateWasm() causes -sWASMFS builds to die horribly

i also tried version 3.1.21, with the same results. Browsers Chrome v105 and v107 were tried, with identical results.

**Failing command line in full:**

It's not quite that simple, unfortunately.

We have a large project (the upcoming official sqlite3 wasm build) for which we are trying to customize the WASM imports. Apparently the only way to do that with Emscripten is to provide a custom Module.instantiateWasm() and modify the imports object which gets passed to it.

Our custom loader works wonderfully in every build combination we've tried but dies horribly in an -sWASMFS build.

The loader:

```js
Module['instantiateWasm'] = function callee(imports,onSuccess){
imports.foo = function(){}; // the whole goal of these acrobatics is to be able to customize the imports
console.warn("instantiateWasm() uri =",callee.uri, self.location.href);
const wfetch = ()=>fetch(callee.uri, {credentials: 'same-origin'});
const loadWasm = WebAssembly.instantiateStreaming
? function loadWasmStreaming(){
return WebAssembly.instantiateStreaming(wfetch(), imports)
.then((arg)=>onSuccess(arg.instance, arg.module));
}
: function loadWasmOldSchool(){ // Safari < v15
return wfetch()
.then(response => response.arrayBuffer())
.then(bytes => WebAssembly.instantiate(bytes, imports))
.then((arg)=>onSuccess(arg.instance, arg.module));
};
loadWasm();
return {};
};
/*
It is literally impossible to reliably get the name of _this_ script
at runtime, so impossible to derive X.wasm from script name
X.js. Thus we need, at build-time, to redefine
Module['instantiateWasm'].uri by appending it to a build-specific
copy of this file with the name of the wasm file. This is apparently
why Emscripten hard-codes the name of the wasm file into their glue
scripts.
*/
Module['instantiateWasm'].uri = 'sqlite3-wasmfs.wasm';
```

That runs just fine until a build with -sWASMFS is used, at which point it dies during startup after triggering the loader several times (presumably once per worker thread):

```
sqlite3-wasmfs.worker.js:28 worker.js onmessage() captured an uncaught exception: TypeError: Cannot read properties of undefined (reading '_emscripten_thread_init')
threadPrintErr @ sqlite3-wasmfs.worker.js:28
self.onmessage @ sqlite3-wasmfs.worker.js:161
sqlite3-wasmfs.worker.js:28 TypeError: Cannot read properties of undefined (reading '_emscripten_thread_init')
at Object.__emscripten_thread_init (sqlite3-wasmfs.js:1021:13)
at self.onmessage (sqlite3-wasmfs.worker.js:97:41)
```

The failing line is:

```js
// Pass the thread address to wasm to store it for fast access.
Module['__emscripten_thread_init'](e.data.pthread_ptr, /*isMainBrowserThread=*/0, /*isMainRuntimeThread=*/0, /*canBlock=*/1);
```
