7163 because the inline candidate calls alloca or uses sjlj exceptions.
7164 (limits_allow_inlining): this new function to check if the inlining
7165 limits are satisfied. Throttle from currfn_max_inline_insns, not from
7166 MAX_INLINE_INSNS_SINGLE. The latter only makes sense if
7167 MAX_INLINE_INSNS_AUTO and MAX_INLINE_INSNS_SINGLE are equal.

7170 inlinable_function_p
7171 (expand_call_inline): Use limits_allow_inlining() when not in
