cmd/internal/obj, cmd/link, runtime: increase stack limit to accommodate larger frames on ppc64x

Browse source 
Larger stack frames mean nosplit functions use more stack and so the limit
needs to increase.

The change to test/nosplit.go is a bit ugly but I can't really think of a
way to make it nicer.
