6261 because the inline candidate calls alloca or uses sjlj exceptions.
6262 (limits_allow_inlining): this new function to check if the inlining
6263 limits are satisfied. Throttle from currfn_max_inline_insns, not from
6264 MAX_INLINE_INSNS_SINGLE. The latter only makes sense if
6265 MAX_INLINE_INSNS_AUTO and MAX_INLINE_INSNS_SINGLE are equal.

6268 inlinable_function_p
