5824 because the inline candidate calls alloca or uses sjlj exceptions.
5825 (limits_allow_inlining): this new function to check if the inlining
5826 limits are satisfied. Throttle from currfn_max_inline_insns, not from
5827 MAX_INLINE_INSNS_SINGLE. The latter only makes sense if
5828 MAX_INLINE_INSNS_AUTO and MAX_INLINE_INSNS_SINGLE are equal.

5831 inlinable_function_p
5832 (expand_call_inline): Use limits_allow_inlining() when not in
