3215 because the inline candidate calls alloca or uses sjlj exceptions.
3216 (limits_allow_inlining): this new function to check if the inlining
3217 limits are satisfied. Throttle from currfn_max_inline_insns, not from
3218 MAX_INLINE_INSNS_SINGLE. The latter only makes sense if

3222 inlinable_function_p
