Raise the relaxed limit which is used for tests.

Remind me again why don't we do -Wno-frame-larger-than (or something to that
effect) for tests?  Is it just because "We should fix it at some point"?  I
can't really recall the reasoning behind that (and if it is still valid) even
though I already asked for it.
