990 limits are satisfied. Throttle from currfn_max_inline_insns, not from
991 MAX_INLINE_INSNS_SINGLE. The latter only makes sense if

996 (expand_call_inline): Use limits_allow_inlining() when not in
997 unit-at-a-time mode to decide on inlining. Don't use DID_INLINE_FUNC,
998 instead see if the function was declared `inline'.
