                    checks with compile-time `__traits(isZeroInit, T)`

With the new `__traits(isZeroInit)` (https://github.com/dlang/dmd/pull/8583) we can check at compile-time if a type has a zero initializer. Aside from removing a branch and some dead code, removing a use of `TypeInfo` is a step towards -betterC compatibility.
