[llvm] Fix type mismatch in ARM calling convention ternary (PR #180872)

[Eric Christopher via llvm-commits]

https://github.com/echristo created https://github.com/llvm/llvm-project/pull/180872

### Summary

Fix type mismatch in ternary that causes GCC `-Werror=extra` to fail.

#### Details

GCC's `-Werror=extra` enforces stricter type consistency in ternary expressions, in this case const-qualified enum variable with enum literals.

### Tested

- Built with ToT clang and GCC 13.3.0 on Linux x86_64 (not really because there are other warnings, but this one is gone).
- All existing tests pass
