LLVM 13+ doesn't recognize `-stack-alignment` option
## Summary When using `-mavx` with recent LLVM backend (LLVM 13 or later), LLVM optimizer fails with ``` opt-13: Unknown command line argument '-stack-alignment=32'. Try: 'opt-13 --help' opt-13: Did you mean '--stackrealign=32'? ``` ## Steps to reproduce ``` $ cat > Hello.hs main = putStrLn "Hello world!" $ ghc-9.6.2 -pgmlo opt-13 -pgmlc llc-13 -fllvm -mavx Hello.hs [1 of 2] Compiling Main ( Hello.hs, Hello.o ) opt-13: Unknown command line argument '-stack-alignment=32'. Try: 'opt-13 --help' opt-13: Did you mean '--stackrealign=32'? <no location info>: error: `opt-13' failed in phase `LLVM Optimiser'. (Exit code: 1) ``` ## Expected behavior The program should compile and link without problems. ## Environment * GHC version used: 9.6.2 and master * Operating System: Linux * System Architecture: x86_64
