1419 because the inline candidate calls alloca or uses sjlj exceptions.
1420 (limits_allow_inlining): this new function to check if the inlining
1421 limits are satisfied. Throttle from currfn_max_inline_insns, not from
1422 MAX_INLINE_INSNS_SINGLE. The latter only makes sense if
1423 MAX_INLINE_INSNS_AUTO and MAX_INLINE_INSNS_SINGLE are equal.

1426 inlinable_function_p
