6701 because the inline candidate calls alloca or uses sjlj exceptions.
6702 (limits_allow_inlining): this new function to check if the inlining
6703 limits are satisfied. Throttle from currfn_max_inline_insns, not from
6704 MAX_INLINE_INSNS_SINGLE. The latter only makes sense if
6705 MAX_INLINE_INSNS_AUTO and MAX_INLINE_INSNS_SINGLE are equal.

6708 inlinable_function_p
