No, that's not true. Let's consider an Ada caller and a C callee. With the
old code (mine as you remarked): caller_fun->can_throw_non_call_exceptions is
true and callee_fun->can_throw_non_call_exceptions is false, so the above test
is false and we can inline. With the new code (yours): check_match is true
and opt_for_fn (callee->decl, flag_non_call_exceptions) is false, so we cannot
inline.
