Reverts llvm/llvm-project#118734 There are currently some specific versions of MSVC that are miscompiling this code (we think). We don't know why as all the other build bots and at least some folks' local Windows builds work fine. This is a candidate revert to help the relevant folks catch their builders up and have time to debug the issue. However, the expectation is to roll forward at some point with a workaround if at all possible.
