Duncan P. N. Exon Smith dc6a335d3d IR: Move creation logic down to MDTuple, NFC
Move creation logic for `MDTuple`s down where it belongs.  Once there
are a few more subclasses, these functions really won't make much sense
here (the `friend` relationship was already awkward).  For now, leave
the `MDNode` versions around, but have it forward down.
