[PATCH olang v1 0/5] Refactors to support semantics

[Carlos Maniero <carlos@maniero.me>]

The semantics is an important part of a compiler but we have postpone
handling it so far. But the cost came, and we started to see some extra
responsibility on the codegen layer because of the lack of semantics.

This patchset does not address semantics per si, but it cover several
tech debts to start supporting it.

Carlos Maniero (5):
  type_checker: rename checker to type_checker
  ast: remove redundancy on ast_node base fields
  ast: unary: rename ast_unary.expr to ast_unary.operand
  ast: remove expr reference from return and var assign nodes
  semantics: add scope to all nodes
