/**
* `t` should be a function that takes at least three arguments:
*
* - the name of the test;
* - the expected error (to be passed to `assert_throws_js`);
* - a function that takes a `WasmModuleBuilder` and initializes it;
* - (optionally) an options object.
*
* The function is expected to create a test that checks if instantiating a
* module with the result of the `WasmModuleBuilder` and the options object
* (if any) yields the correct error.
