Static type conversion with Bool

[oschulz]

We currently have

julia> promote(static(5), static(true))
(5, 1)

julia> promote(static(true), true)
(static(true), static(true))

julia> promote(static(true), static(true))
(static(true), static(true))

julia> promote(static(true), true)
(static(true), static(true))

Is this deliberate, or some unintended effect? It seems weird that we promote static integer and static bool to non-static, and promote static integer and non-static bool to static.
