Self-referencing spread recursive loop #12808

  1. Use checkExpression in checkSpreadExpression 

    Not checkExpressionCached. checkExpressionCached ignores ongoing control
flow analysis, which causes the following loop to make the compiler
recur infinitely:

```ts
let a = []
for (const x of []) {
    a = [...a]
}
```
