Rollup merge of rust-lang#114612 - lqd:east-17-warning, r=nikic

update llvm-wrapper include to silence deprecation warning

Includes of `include/llvm/Support/Host.h` now emit a deprecated warning: `warning: This header is deprecated, please use llvm/TargetParser/Host.h`.

I don't believe we are using this include.

I don't believe we need to bump the `download-ci-llvm` stamp since these warnings are emitted while building the `llvm-wrapper`.
