A previous patch merged the static and bitcode versions of the deviceRTL. We previously used the static library's separate compilation to set a special flag that prevented `IsSPMDMode` from being put in the used list and preventing it from being optimized out. When they were merged we could no longer do this separate compilation that allowed users of LTO to get more optimal code. This patch rearranges the code. The `IsSPMDMode` global is now transitively used by its inclusion in the changed `__keep_alive` function. This allows us to then manually delete the `__keep_alive` function from the module when building the static library via `llvm-extract`. The result is that the bitcode library correctly will maintain the needed shared state, while the static library will be able to internalize it and optimize it out.
