**Description:**
This is a part of https://github.com/swc-project/swc/pull/9230. I
profiled the performance, and `thread_local` took too long to get the
address of the thread-local variable. So, I inlined the reference into
the allocator.

**Description:**
Helper methods were exporting twice, `_` and it's own function name.
We can map the build script to export `_` as it's own name (filename).
Therefore we export only once as `_`, and map the name on the build
script.
```js
// helpers/_foo.js
function _foo() {
// ...
}
export { _foo as _ }
```
```js
// index.js
// We know the func name will be `_foo` based on the filename.
export { _ as _foo } from '_foo.js'
```
Closes#9203

**Description:**
This PR changes the AST node construction code to use `.into()` or `::from()` to make changing the boxed-ness of the AST node easier. I used `ast-grep` to make large changes across codebase.
