Introduce TaggedUnion as the low-level basis for TaggedAlgebraic.
...
TaggedUnion has a number of convenience features compared to TaggedAlgebraic that are possible because of the missing dynamic dispatch functionality. If the latter is not required, TaggedUnion provides a much less complex and more robust way to store a fixed set of types/kinds.

Enable proper default initialization.
...
Since @disable this() still leaves an invalid .init open, TaggedAlgebraic.init has now been changed to always contain the .init value of the first specified sub type.
Note that this change is restricted to DMD 2.072 and up, because earlier versions of DMD do not allow postblits or destructors within unions and using a union appears to be the only way to implement this.

Rename "type" to "kind".
...
Although there will be situations where the enum names equal the name of the types stored in a TaggedAlgebraic, "type" is often not the right term. It's also possible to define multiple fields of the same type, but with different names. "Kind" is used now as a more generic alternative.
