Summary
When I build rustc with the local llvm, I want to know with what external LLVM versions will rustc work.
https://github.com/rust-lang/rust/pull/122649 upgrades in March the minimum external LLVM version to 17.
https://github.com/rust-lang/rust/pull/127513 updates in July LLVM to version 19.
But the above links do not touch the user-visible documentation. For me it is unclear, if I want to compile rust 1.82 later, if I can use LLVM 18, or I must use LLVM 19. I find no place, where this is documented.
- Document the minimal and maximal versions for external LLVM supported by rustc.

Research direction
Start by reading the linked pull requests #122649 and #127513 and searching the repository for existing user-facing LLVM version documentation. Document the minimum and maximum external LLVM versions supported by rustc, including the version information relevant to the cited releases, and verify that users can find it.
