  Log Message:
  -----------
  Reland 9f3fdb0d7fab: [Driver] Use VFS to check if sanitizer blacklists exist

With updates to various LLVM tools that use SpecialCastList.

It was tempting to use RealFileSystem as the default, but that makes it
too easy to accidentally forget passing VFS in clang code.
