  [Clang][CodeGen] Fix bad codegen when building Clang with latest MSVC (#102681)

Before this PR, when using the latest MSVC `Microsoft (R) C/C++
Optimizing Compiler Version 19.40.33813 for x64` one of the Clang unit
test used to fail: `CodeGenObjC/gnustep2-direct-method.m`, see full
failure log:
[here](https://github.com/llvm/llvm-project/pull/100517#issuecomment-2266269490).

This PR temporarily shuffles around the code to make the MSVC inliner/
optimizer happy and avoid the bug.
