[llc] LLVM ERROR: Broken module found, compilation aborted!

I'm using LLVM 22.1.3 on Windows (clang+llvm-22.1.3-x86_64-pc-windows-msvc.tar.xz from releases).
Running command `llc -O=3 -filetype=obj -mtriple=arm64ec-pc-windows-msvc test.bc` gives me following error:
```
comdat global value has private linkage
ptr @"#__return_procedure"
LLVM ERROR: Broken module found, compilation aborted!
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace and instructions to reproduce the bug.

test.bc is in the archive:
[test.zip](https://github.com/user-attachments/files/26829104/test.zip)

Reproduce the failure with the attached test.bc archive using the reported llc command and the arm64ec-pc-windows-msvc target. Start by inspecting the broken-module diagnostic and the generated stack dump to identify the relevant compiler component. Done means the reproducer no longer aborts with the private-linkage COMDAT error.
