Bob Haarman 50bb177930 LTO: don't fatal when value for cache key already exists ... Summary: LTO/Caching.cpp uses file rename to atomically set the value for a cache key. On Windows, this fails when the destination file already exists. Previously, LLVM would report_fatal_error in such cases. However, because the old and the new value for the cache key are supposed to be equivalent, it actually doesn't matter which one we keep. This change makes it so that failing the rename when an openable file with the desired name already exists causes us to report success instead of fataling.
