The difference in stack usage is caused by ivopts. -fno-ivopts reduces 4.1
stack usage to 12 bytes and 200 bytes with --param inline-unit-growth=1000000
Especially in the second case ivops should probably trottle down after some loop
nest as it makes no sense to increase number of induction variables for each of
loop of nest8.
I will look into saner recursive inlining limits too.

There is no recursive inlining happening at least on 4.1 because of overall unit
growth limit is met, so we do remarkably worse compared to 3.4 anyway.
Enabling recursive inlining makes it very active. This is side effect of last
growth model changes and I need to trottle this somehow.
