[testharness.js] Revert assert-tracking code

Despite a series of attempts to fix the performance regressions from
this code (largely by propagating the value of 'output' properly), we
have hit a wall with tests that run in workers. There is no way
currently for a testharness.js script loaded in a worker to know that it
shouldn't be tracking asserts, and this is causing a large performance
regression on Chromium's bots.

This reverts commit 934077ad8594041ef09a19181434f32c10c34d20.

Because I did not revert a commit in the middle of these (that added
unrelated debug logging), I had to do a few fixups for the reverts.
(I.e. they were not all pure reverts).
