Revert of [turbofan] Fix bunch of tests failing with --turbo-deoptimization. (patchset #1 id:1 of https://codereview.chromium.org/786333004/ )
...
Reason for revert:
This changes layout test expectations. I ran a bisect over the layout tests:
Bad:
http://build.chromium.org/p/client.v8/builders/V8-Blink%20Linux%2032/builds/1600
Good:
http://build.chromium.org/p/client.v8/builders/V8-Blink%20Linux%2032/builds/1599
If this is intentional please first land a CL with manualrebaseline test expectations for the changed tests and then reland.

This time we simply undo the change introduced by the PPC port for
this test. No idea why it should be necessary, and Windows XP
obviously doesn't give us that much stack, anyway.

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. :-/
