Instead of leaving array bounds as whatever integer type they arrive as, convert them to the `IntLiteral` type as part of forming an `ArrayType`. This ensures that array types canonicalize properly even when the bounds are specified with different types. Create an empty generic definition for a generic builtin function to avoid this causing "use of undefined generic function" errors.
