GCC caches the whether a function is a leaf in crtl->is_leaf. Using this

I forgot to ask, would it be reasonable to add an assert to check we're not in
a sequence in leaf_function_p? I guess this will trigger on several targets
(leaf_function_p is used in several backends) but it's a real bug if
crtl->is_leaf is true.
Can it wait for the next stage1? I'd hate to start tripping the assert
all over the place at this point in the release cycle.
