2773 (limits_allow_inlining): this new function to check if the inlining
2774 limits are satisfied. Throttle from currfn_max_inline_insns, not from
2775 MAX_INLINE_INSNS_SINGLE. The latter only makes sense if
2776 MAX_INLINE_INSNS_AUTO and MAX_INLINE_INSNS_SINGLE are equal.

2779 inlinable_function_p
