* avoid duplicating impure initializers in object rest destructuring * reuse existing VariableDeclarations in object rest destructuring, to fix two issues: 1. inserting an additional VariableDeclaration after the current one may change order of operations, which is unsafe if a future VariableDeclarator refers to a destructured variable. 2. The entire VariableDeclaration is removed when all properties are rest properties, indiscriminately removing other variables
