Lift VFS from clang to llvm (NFC)
This patch moves the virtual file system form clang to llvm so it can be
used by more projects.
Concretely the patch:
- Moves VirtualFileSystem.{h|cpp} from clang/Basic to llvm/Support.
- Moves the corresponding unit test from clang to llvm.
- Moves the vfs namespace from clang::vfs to llvm::vfs.
- Formats the lines affected by this change, mostly this is the result of
the added llvm namespace.
