This reverts commit d4c7e9fc63c10dbab0c30186ef8575474a704496. This is done in order to address the failure of CrWinClangLLD etc. bots. These throw an error of "side-by-side configuration is incorrect" during compilation, which sounds suspiciously related to these manifest changes. Revert "Switch external cvtres.exe for llvm's own resource library." This reverts commit 71fe8ef283a9dab9a3f21432c98466cbc23990d1. llvm-svn: 306618
