Hi Michael,
since we were running these tests without these limits for months (because we
ignored the max limits flags) and I cannot think about a reason why the limits
make sense, I am removing them from the tests.

--max-new-space-size makes sense when you want to ensure that even a relatively
short-running test triggers one or more allocation failures and resulting
scavenges. Especially for the regression tests, I would guess that the flag was
necessary to reproduce the original bug.
--max-old-space-size makes sense when a test tests OOM behavior, but it doesn't
look like any of the tests you modified did that, so it's probably fine to
remove that flag.
