This is a work in progress.

We currently have our own testing package, and while it works, ideally we'd use the version in the standard library. This PR is a start on that: make tinygo-test passes, but make tinygo-test-baremetal for example doesn't. More changes will be needed.

An example PR that wouldn't be needed anymore if we used the Go standard library testing package: #5058

Oh, huh. This fails because AllocsPerRun actually works (at least on wasip1) and our GC escape analysis isn't as good as the escape analysis in upstream Go. So tests start failing that passed before, but what changed is that AllocsPerRun actually checks allocations.

Not sure what to do here. We could modify runtime.ReadMemStats to run fake numbers during testing, but that doesn't seem like a clean solution. Or, maybe, try to improve the GC so that these tests start passing.
