Sorry for the noise, I managed to miss a bunch of recent regressions of
include orderings here. This should actually sort all the includes for
Clang. Again, no functionality changed, this is just a mechanical
cleanup that I try to run periodically to keep the #include lines as
regular as possible across the project.

Mixed path separators (ie, both / and \\) can mess up the sort order
of the VFS map when dumping module dependencies, as was recently
exposed by r224055 and papered over in r224145. Instead, we should
simply use native paths for consistency.
This also adds a TODO to add handling of .. in paths. There was some
code for this before r224055, but it was untested and probably broken.

components. These sometimes get synthetically added, and we don't want -Ifoo
and -I./foo to be treated fundamentally differently here.

This reimplements part of r211303 in a bit of a cleaner way. Doing so
allows us to use a proper absolute path when calling addFileMapping
rather than relying on a substring being one, which should fix the
tests on Windows.

This adds the -module-dependency-dir to clang -cc1, which specifies a
directory to copy all of a module's dependencies into in a form
suitable to be used as a VFS using -ivfsoverlay with the generated
vfs.yaml.
This is useful for crashdumps that involve modules, so that the module
dependencies will be intact when a crash report script is used to
reproduce a problem on another machine.
We currently encode the absolute path to the dump directory, due to
limitations in the VFS system. Until we can handle relative paths in
the VFS, users of the VFS map may need to run a simple search and
replace in the file.
