9084 because the inline candidate calls alloca or uses sjlj exceptions.
9085 (limits_allow_inlining): this new function to check if the inlining
9086 limits are satisfied. Throttle from currfn_max_inline_insns, not from
9087 MAX_INLINE_INSNS_SINGLE. The latter only makes sense if
9088 MAX_INLINE_INSNS_AUTO and MAX_INLINE_INSNS_SINGLE are equal.

9091 inlinable_function_p
9092 (expand_call_inline): Use limits_allow_inlining() when not in
