Adding the version that caches directory contents.

This has the problem the it doesn't play with modules, the rewriter, and possibly others, because they write to the file system without any way for the vfs to find out. I've tried to find a good way to fix that, but didn't come up with anything. One way would be to maintain a global counter like llvm::sys::fileSystemChangeCount which when changed would invalidate the maps, but I don't know if that would be acceptable.
