Reordering `OS` and `PassMgrF` should fix the asan failure that's caused by OS being destroyed before `PassMgrF` deletes the AsmPrinter. As shown in[ this asan run ](https://lab.llvm.org/buildbot/#/builders/52/builds/7340/steps/12/logs/stdio) ``` This frame has 15 object(s): [32, 48) 'PassMgrF' (line 154) [64, 1112) 'Buf' (line 155) [1248, 1304) 'OS' (line 156) <== Memory access at offset 1280 is inside this variable ``` which indicates an ordering problem. This should help to fix all the sanitizer failures caused by the test `X86MCInstLowerTest.cpp` that's introduced by [this PR](https://github.com/llvm/llvm-project/pull/133352#issuecomment-2780173791).
