[ignition] Eliminate hole checks where statically possible for loads and stores Move hole check logic from full-codegen into scope analysis, and store the "needs hole check" bit on VariableProxy. This makes it easy to re-use in any backend: it will be trivial to extend the use of this logic in, e.g., full-codegen variable stores. While changing the signatures of the variable loading/storing methods in Ignition, I took the liberty of replacing the verb "Visit" with "Build", since these are not part of AST visiting.
