This is not a true regression, because the combination of out parameter +
disabled default construction struct is essentially invalid.

http://dlang.org/function#parameters
"parameter is initialized upon function entry with the default value for its
type"

Such struct does not have "default value", because its construction always
needs explicit constructor call with one or more arguments.

>From 2.063, such function call was made invalid, but the declaration is still
accepted. Therefore this issue should be marked an "accepts-invalid".
