1457 because the inline candidate calls alloca or uses sjlj exceptions.
1458 (limits_allow_inlining): this new function to check if the inlining
1459 limits are satisfied. Throttle from currfn_max_inline_insns, not from
1460 MAX_INLINE_INSNS_SINGLE. The latter only makes sense if

1464 inlinable_function_p
