Rollup test to plugin load hook context api.

```
 "rollup@function@modify-meta: allows to freely modify moduleInfo.meta and maintain object identity",
 "rollup@function@perf-adds-plugin-context-to-plugins: Adds plugin context to plugins with perf=true",
 "rollup@function@preload-loading-module: waits for pre-loaded modules that are currently loading"
```
This test case failed because lost some load context API.
