[SDAG] Make the new zext-vector-inreg node default to expand so targets

don't need to set it manually.

This is based on feedback from Tom who pointed out that if every target
needs to handle this we need to reach out to those maintainers. In fact,
it doesn't make sense to duplicate everything when anything other than
expand seems unlikely at this stage.
