7176 because the inline candidate calls alloca or uses sjlj exceptions.
7177 (limits_allow_inlining): this new function to check if the inlining
7178 limits are satisfied. Throttle from currfn_max_inline_insns, not from
7179 MAX_INLINE_INSNS_SINGLE. The latter only makes sense if
7180 MAX_INLINE_INSNS_AUTO and MAX_INLINE_INSNS_SINGLE are equal.
7182 (tree_inlinable_function_p): Make a bool. Update call to
7183 inlinable_function_p
7184 (expand_call_inline): Use limits_allow_inlining() when not in
7185 unit-at-a-time mode to decide on inlining. Don't use DID_INLINE_FUNC,
7186 instead see if the function was declared `inline'.
