Nicely composable NodeBuilderGenerator, +mixins. 

This cleans up a lot of stuff and reduces the amount of boilerplate
content that's just generating monomorphizing error method stubs.

The nodeGenerator mixins now also use the node mixins.  I don't know
why I failed to do that from the start; I certainly meant to.
It results in shorter generated code, and the compiler turns it into
identical assembly.
