bors 26f4b72724 Auto merge of #115418 - Zoxc:freeze-source, r=oli-obk
Use `Freeze` for `SourceFile`

This uses the `Freeze` type in `SourceFile` to let accessing `external_src` and `lines` be lock-free.

Behavior of `add_external_src` is changed to set `ExternalSourceKind::AbsentErr` on a hash mismatch which matches the documentation. `ExternalSourceKind::Unneeded` was removed as it's unused.

Based on https://github.com/rust-lang/rust/pull/115401.

The codegen crate contains the code to convert from MIR into LLVM IR, and then from LLVM IR into machine code. In general it contains code that runs towards the end of the compilation process.

For more information about how codegen works, see the rustc dev guide.
