10965 because the inline candidate calls alloca or uses sjlj exceptions.
10966 (limits_allow_inlining): this new function to check if the inlining
10967 limits are satisfied. Throttle from currfn_max_inline_insns, not from
10968 MAX_INLINE_INSNS_SINGLE. The latter only makes sense if
10969 MAX_INLINE_INSNS_AUTO and MAX_INLINE_INSNS_SINGLE are equal.
