Ben Langmuir 2c9af44c26 When module umbrellas change, rebuild them
With the VFS, it is easy to hit modified umbrellas by overriding the
umbrella header, and what we want is to rebuild, not to fail.

Ben Langmuir f9a6ac213a Add a test where the module map is overriden in the vfs
Specifically, we pass two -ivfsoverlay yaml files, and the topmost one
remaps the module map file.

Ben Langmuir a6f8ca8c5f Support relative paths in VFSFromYAML
Use llvm::sys::fs::make_absolute to get an absolute path before
matching. Also, allow "." directories to enable testing.  ".." is still
not supported, and will require crossing file system boundaries to
implement correctly.

Ben Langmuir d066d4c849 Reapply fixed "Honour 'use-external-names' in FileManager"
Was r202442

There were two issues with the original patch that have now been fixed.
1. We were memset'ing over a FileEntry in a test case. After adding a
   std::string to FileEntry, this still happened to not break for me.
2. I didn't pass the FileManager into the new compiler instance in
   compileModule. This was hidden in some cases by the fact I didn't
   clear the module cache in the test.

Also, I changed the copy constructor for FileEntry, which was memcpy'ing
in a (now) unsafe way.

Ben Langmuir 09e0d5c1bb Honour 'use-external-names' in FileManager
Pass through the externally-visible names that we got from the VFS down
to FileManager, and test that this is the name showing up in __FILE__,
diagnostics, and debug information.

Ben Langmuir 801272a98c Add a driver option -ivfsoverlay
Reads the description of a virtual filesystem from a file and overlays
it over the real file system.
