Jon Ross-Perkins bf89652a4d Move common entity fields to a 'base' struct. (#4161)
I'd considered moving DeclParams uses over, but when handling qualified
names, there's a parse node instead of an instruction. I did try to
unify a couple other uses though, including adding MergeDefinition. I
expect `interface` will use a little more once it's more completely
implemented, but maybe I'm wrong about that.
