8120 because the inline candidate calls alloca or uses sjlj exceptions.
8121 (limits_allow_inlining): this new function to check if the inlining
8122 limits are satisfied. Throttle from currfn_max_inline_insns, not from
8123 MAX_INLINE_INSNS_SINGLE. The latter only makes sense if
8124 MAX_INLINE_INSNS_AUTO and MAX_INLINE_INSNS_SINGLE are equal.

8127 inlinable_function_p
