Adding HardLink Support to VirtualFileSystem.
Summary:
Added support of creating a hardlink from one file to another file.
After a hardlink is added between two files, both file will have the same:
1. UniqueID (inode)
2. Size
3. Buffer
This will bring replay of compilation closer to the actual compilation. There are instances where clang checks for the UniqueID of the file/header to be loaded which leads to a different behavior during replay as all files have different UniqueIDs.
