https://ci.chromium.org/ui/p/chromium/builders/try/linux_chromium_asan_rel_ng/1104768/test-results

Original change's description:
> Reland "heap: Force incremental marking in C++ only workloads"
>
> This is a reland of commit 4fde3328
>
> Most recent fix made Oilpan aware of --single-threaded-gc which
> is necessary as GCs are more eagerly scheduled in tests.

> Original change's description:
> > heap: Force incremental marking in C++ only workloads
> >
> > ... when above a certain minimum threshold. This is to guard against
> > memory running away in scenarios where the JS heap is empty and
> > there's only high throughput C++ allocations that don't allow for a
> > memory reducer GC to kick in.
> >
> > This logic should be revisited after Oilpan's young generation
> > collector is implemented which may allow switching to a more efficient
> > shrinking strategy for initial heap setup.
