[TEST] Host Reduction

* SUMMARY
"(host)" is confusing in cases where I would expect to see JS name.

* TEST:
<script>
setTimeout(function() {
    for (var i = 0; i < 10000; ++i)
        new Error();
}, 100);
</script>

* NOTES
- Legacy Profiler shows "Error"
- Sampling Profiler shows "(host)"

Is there some way we can get some display name for certain host functions?
