This fixes V8 issue 989. Before, assignments used the AST ID of the assignment expression to mark the side effect of the store, which became a target for deoptimization bailout for code after the assignment. In effect contexts this environment included the value of the assignment, which was unexpected by the unoptimized code. Now we introduce a new assignment ID for AST node types that include an assignment (Assignment, CountOperation, and ForInStatement) and use it for the side effect of the store.
