`match_expression!` + `self.to_expression()` seems like doing to the
same thing twice.
Incorrect matches should be caught unit tests.

i couldn't really write a test for this, as it only happens when codegen + minifier are used together.
Regression should be prevented by the 262 suite in #8256 (failed CI run before i implemented this fix: https://github.com/oxc-project/oxc/actions/runs/12621310419/job/35168016825 )

perf(sourcemap): improve perf of search_original_line_and_column ( #7926 )
...
this seems to show a decent speed up on perf.
the thinking behind this change is:
1. subsequent calls to `search_original_line_and_column` will **never**
look at back at lines it has already searched
2. binary search is faster in this case as typically `idx` is only
increased by a small amount
Given this, we can skip checking a bunch of lines (that will never
return true) improving performance.
This is a very hot path.
```

refactor(global): sort imports ( #7883 )
...
Pure refactor. Re-order imports for clarity:
1. `std`
2. External crates
3. `oxc_*` crates
4. Current crate `use crate::...`
5. Super `use super::...`
6. Local modules
This order is from "furthest away" to "closest". This makes it clearer to see what is coming from where.
`cargo +nightly fmt` (#7877 ) did a lot of the work, but unfortunately `rustfmt` does not have an option to (a) put workspace crates in a separate block from external crates and (b) move `mod` statements to after `use` statements.

perf(codegen): faster writing indentation ( #7820 )

Write indentation faster. Previously was writing indentation to buffer with a call to `memset`, which is relatively expensive. Where indentation `<= 16` (common case), write 16 tabs with a single 16-byte XMM write, which is faster.

This PR does not upgrade rustc. Only changes are applied.
We cannot upgrade to the lastet Rust version yet due to wasm-bindgen
breaking some generated types.
THere's also some elided lifetimes in `**/generated/**`, which requires
modification to ast tools.
