2796 because the inline candidate calls alloca or uses sjlj exceptions.
2797 (limits_allow_inlining): this new function to check if the inlining
2798 limits are satisfied. Throttle from currfn_max_inline_insns, not from
2799 MAX_INLINE_INSNS_SINGLE. The latter only makes sense if

2803 inlinable_function_p
