8116 because the inline candidate calls alloca or uses sjlj exceptions.
8117 (limits_allow_inlining): this new function to check if the inlining
8118 limits are satisfied. Throttle from currfn_max_inline_insns, not from
8119 MAX_INLINE_INSNS_SINGLE. The latter only makes sense if
8120 MAX_INLINE_INSNS_AUTO and MAX_INLINE_INSNS_SINGLE are equal.

8123 inlinable_function_p
