The function resultsToWasmFields was originally for only wasmimport. I adopted it for wasmexport as well, but forgot to update a few places that were wasmimport-specific. This leads to compiler panic if an invalid result type is passed, and also unsafe.Pointer not actually supported. This CL fixes it. Updates #65199.
