Roll forward stateful loop_emscripten changes. (#11801)

This is a roll forward of https://github.com/iree-org/iree/pull/11507

Successful CI run:
https://github.com/iree-org/iree/actions/runs/3897710708/jobs/6655737094

I had been testing locally with
[`experimental/web/testing/build_tests.sh`](https://github.com/iree-org/iree/blob/main/experimental/web/testing/build_tests.sh),
which sets `-DCMAKE_BUILD_TYPE=RelWithDebInfo`. The CI uses
[`build_tools/cmake/build_runtime_emscripten.sh`](https://github.com/iree-org/iree/blob/main/build_tools/cmake/build_runtime_emscripten.sh),
which leaves the build type unset and defaults to `Release`.

Release builds were failing with `SyntaxError: Unexpected token
(1:72626)` in `/emsdk/upstream/emscripten/tools/acorn-optimizer.js:1852`
with this code:

While `for (const [key, value] of Object.entries(object1))` is the
recommended way to iterate through an object's enumerable string-keyed
property key-value pairs
([source](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/entries)),
Emscripten does not appear to support that newer syntax out of the box.
