    Revert "MSVC release builds: Ensure that /LTCG is used"
    
    As we now ensure that items using GResources and GConstructors are always
    referenced so that the linker does not optimize them out in a default
    Release build, we no longer need to enforce the use of /LTCG, so
    /LTCG:incremental will work as well.
    
    This reverts commit fc5394e7ca78d6d6272a3591236f99c11ffc5111.
