PPC aftermath: Fix regress-crbug-178790.

The test fails on XP only, so let's tentatively raise the stack limit more. We probably need to investigate what a tighter limit might be and (more importantly) what the underlying reason for the failure is.

Hopefully 1800kB is enough, we can't test this via try jobs, because we don't have XP try bots. :-/
