Enable function names by default in all test suites?

Its pretty unhelpful to see reports from builders that look like this one: https://github.com/emscripten-core/emscripten/issues/15468

```

```

Having the names of the intervening functions would make diagnostics much faster.

I believe the cheapest way to do this is to run all tests with `--profiling-functions` by default. (some tests may want to opt out of course).
