[IR] Final preparation to autogenerate IR declaration implementations

IR expressions are left out for now, because unlike declarations,
which are mostly created via IrFactory, expressions' constructors are
widely used, and it's hard to replicate the exact signatures of those
constructors with the tree generator.

Therefore, some other approach is expected to be taken when generating
them in the future.
