Use error-on-mismatch policy for PAuth module flags. This agrees with Clang, and avoids an error when using LTO with mixed C/Rust. LLVM considers different behaviour flags to be a mismatch, even when the flag value itself is the same. This also makes the flag setting explicit for all uses of LLVMRustAddModuleFlag. ---- I believe that this fixes #92885, but have only reproduced it locally on Linux hosts so cannot confirm that it fixes the issue as reported. I have not included a test for this because it is covered by an existing test (`src/test/run-make-fulldeps/cross-lang-lto-clang`). It is not without its problems, though: * The test requires Clang and `--run-clang-based-tests-with=...` to run, and this is not the case on the CI. * Any test I add would have a similar requirement. * With this patch applied, the test gets further, but it still fails (for other reasons). I don't think that affects #92885. |

The codegen crate contains the code to convert from MIR into LLVM IR,
and then from LLVM IR into machine code. In general it contains code
that runs towards the end of the compilation process.
For more information about how codegen works, see the rustc dev guide.
