IsZero

[Helton Marques]

There's some reason to not have the function `IsZero` to time.Duration ?

IMO, I think this can be useful: 

```

type Server struct { timeout time.Duration `yaml:"timeout:"` }

...

if srv.timeout.IsZero() { srv.timeout = defaultServerTimeout } 

```

Anyone knows if there's some restriction to not have IsZero() bool functions to defined types as int64 ?

Where you want to write `d.IsZero()`, you can just write `d == 0`.
I'm not sure adding a `IsZero` method is really worth it.

Yeah, I now, but considering these proposal: https://github.com/golang/go/issues/20757 

This function (IsZero) would not bring even more reliable use ?

Sure, if we adopt proposal #20757 we may well need or at least want an
IsZero method. That is a Go 2 proposal, though; for Go 1 I don't see
sufficient benefit.
