3188 (limits_allow_inlining): this new function to check if the inlining
3189 limits are satisfied. Throttle from currfn_max_inline_insns, not from
3190 MAX_INLINE_INSNS_SINGLE. The latter only makes sense if
3191 MAX_INLINE_INSNS_AUTO and MAX_INLINE_INSNS_SINGLE are equal.

3194 inlinable_function_p
3195 (expand_call_inline): Use limits_allow_inlining() when not in
