Rollup merge of #140485 - Jarcho:from_expansion_opt, r=petrochenkov ...

Optimize the codegen for `Span::from_expansion`

See https://godbolt.org/z/bq65Y6bc4 for the difference. the new version is less than half the number of instructions.

Also tried fully writing the function by hand:
```rust
sp.ctxt_or_parent_or_marker != 0
        && (
            sp.len_with_tag_or_marker == BASE_LEN_INTERNED_MARKER
            || sp.len_with_tag_or_marker & PARENT_TAG == 0
        )
```

But that was no better than this PR's current use of `match_span_kind`.
