fix(es/compat): Fix syntax context of async-to-generator (#6741)
**Description:**

Previously, the `async-to-generator` produced invalid AST, in the aspect of span hygiene.

[Playground](https://play.swc.rs/?version=1.3.24&code=H4sIAAAAAAAAAz1MbQqAIBT77yn2UyG6gNQJuoSZRCAa7xkk4d1TicZgH7C5%2B4yUYGPgBE7ZuyWazREmSIVpxiMAcumi0C3ANZxyvQ6%2Fqa8CehxjaGNpOAcLaWjn%2F6KhKN1dGaoULSpfHPTdxn8AAAA%3D&config=H4sIAAAAAAAAA0WOSwrDMAxE76K1F22hXfgE3fQQxlWCi39ICsQY3z12cMlOjObNTIUfW9AVsiFGGheXKGYHDVIysiWXBRQId2kxnrEpwF2QovFv9BmJQQtt2D2GVpROIj9u92enfEqMk1MQXHRLGR02hUzIfL1MXP3f2XpFSN9tCPWccWa%2BoF0Zk3P8mcYxoR3Kj7IYzwAAAA%3D%3D).
It generate two bindings for `args` so it's invalid.

fix(es/minifier): Fix ordering issue of analyzer (#6150)
**Description:**

This is the groundwork for a parallel analyzer. This PR fixes the ordering issue of the analyzer so that the analyzer works identically regardless of the visit order. This patch contains some improvements because previously, we mixed `.and_modify()` and `.or_default()`.

feat(es/minifier): Clone trivial literals in sequential inliner (#6005)
**Description:**

As our minifier is two-pass by default, this is enough.

At the first pass, we inline all numeric literals using sequential inliner, and minifier can then inline constants correctly in the second pass.
