**Description:**
In the default mode, `Box<T>` and `Vec<T>` should work just like them from std.

**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:**
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.
**Description:**
This PR allows `ArrayLit`s to be converted to numbers in the
`cast_to_number` function. This allows expressions using arrays to be
converted to numbers. See some example expressions below that were
previously not able to be computed, but are now able to due to this
change.
```js
+[] // 0
+[[]] // 0
+[1] // 1
+[undefined] // 0
+[null] // 0
+[[1]] // 1
+[,] // 0
+[,,] // NaN
```
Regarding the implementation, arrays are converted to strings, and the
string is then parsed as a number. So arrays like `[]` and `[undefined]`
return `""` which then return `0` when parsed as a string. This is also
why arrays with more than one element can't be parsed because e.g. `[1,
2]` returns `"1,2"`. This procedure follows the ECMAScript
specification.

**Description:**
The original code separately records the usage of variables and checks if there is a closure. Changed to only record variables used in a closure.
**Related issue:**
- Closes https://github.com/swc-project/swc/issues/8010
**Description:**
Given that decorators will be a part of JavaScript, as specified in the [proposal](https://github.com/tc39/proposal-decorators), we retain them in the output rather than reporting an error.

**Description:**
This PR makes `PluginCommentProxy` work by default in `test_fixture()`. This PR adds a scoped-local to `swc_common`, and uses it from `swc_ecma_transforms_testing`.
It can't be tested in the main repository, though. We cannot enable `plugin_mode` of `swc_common` in the main SWC repository.

**Description:**
by symbol name -> by whether it points to global undefined or not.
The updated test results all involve variables with `undefined` ident (although they are indeed uninitialized).
**Related issue:**
- Closes: https://github.com/swc-project/swc/issues/8567
**Description:**
Now, `TokenContext` is 1 byte, so we can increase the stack size for it.

**Description:**
- `TokenContexts` now uses smallvec, as the element type is very small (1 byte) now.
- Some codes are moved to allow CPU to cache code correctly.
**Description:**
`EsConfig` and `TsConfig` sound like a general configuration for the whole language, while actually it's only about parsing.
To avoid a breaking change, I created type aliases that will work without changing the code, while warning the users.
**Related issue:**
- Closes#9089.
**Description:**
In the fast path, we don't even use the buffer.

**Description:**
Coverage gets better if we generate fewer source map entries. This PR only fixes the issue for `"coverageProvider": "v8"`. Much more work is required for the default coverage provider I guess.

https://github.com/getsentry/rust-sourcemap/pull/91 should fix this
issue, but let's revert #9052 for now.

**Description:**
TsPropertySignature can not have params, type params, or an initializer.
**BREAKING CHANGE:**
Yes. Any users looking into these fields should stop - they are always empty.

**Description:**
I mistakenly introduced a performance regression with https://github.com/swc-project/swc/pull/9032. It makes the minifier visit the initializer of variables multiple times - once while normal visiting and once in `hoist_props_of_vars`. This PR fixes it.
**Description:**
Handles
```js
var FRUITS = { MANGO: "mango" }, getMangoLabel = (label) => label[FRUITS.MANGO];
```
while hoisting properties. In the code above, the initializer of the second variable declarator should be visited after hoisting the first variable declarator. Otherwise `FRUITS.MANGO` cannot be handled.
**Related issue:**
- Closes#9030
**Description:**
This reverts commit cc8c1550dd because it caused a regression in the next.js canary.
- Canary version: `15.0.0-canary.12`
**Related issue:**
- Reverts #8986
