Rollup merge of #162034 - saethlin:llvm-version-mismatch-error, r=nnethercote Make the LLVM version mismatch ICE a fatal error It was pointed out to me that the diatnostic in #161788 has the usual ICE messages about how this is a bug and we'd appreciate a report. But it isn't, and a fatal error is a better way to report the problem. Manually tested on MacOS: ``` $ export DYLD_LIBRARY_PATH=/opt/homebrew/opt/llvm@21/lib $ rustc +stage1 --print=sysroot error: LLVM version mismatch: this compiler was built for LLVM 23, but LLVM 21.1.8 was found at /opt/homebrew/Cellar/llvm@21/21.1.8/lib/libLLVM.dylib $ unset DYLD_LIBRARY_PATH $ rustc +stage1 --print=sysroot /Users/ben.kimock/rust/build/aarch64-apple-darwin/stage1 ```
