The `-ivfsoverlay` flag was only being respected when the scanner was instructed to minimize the inputs. This patch respects that flag even in canonical preprocessing mode.
Depends on D135414.

In D92191, a bunch of test cases were added to check `clang-scan-deps` works in `clang-cl` mode as well.
We don't need to duplicate all test cases, though. Testing the few special cases we have in `clang-scan-deps` for `clang-cl` should be good enough:
1. Deducing output path (and therefore target name in our make output).
2. Ignoring `-Xclang` arguments in step 1.
3. Deducing resource directory by invoking the compiler executuable.
This test de-duplicates the extra clang-cl test cases.

This reverts commit 199c39748292cbc89cd148a0d8364ebb1014ec38.
This time, clang-scan-deps's search for output argument in clang-cl command line will now ignore arguments preceded by "-Xclang".
That way, it won't detect a /o argument in "-Xclang -ivfsoverlay -Xclang /opt/subpath"
Initial patch description:
clang-scan-deps contains some command line parsing and modifications.

This commit implements the fast dependency scanning mode in clang-scan-deps: the
preprocessing is done on files that are minimized using the dependency directives source minimizer.
A shared file system cache is used to ensure that the file system requests and source minimization
is performed only once. The cache assumes that the underlying filesystem won't change during the course
of the scan (or if it will, it will not affect the output), and it can't be evicted. This means that the
service and workers can be used for a single run of a dependency scanner, and can't be reused across multiple,
incremental runs. This is something that we'll most likely support in the future though.
Note that the driver still utilizes the underlying real filesystem.
This commit is also still missing the fast skipped PP block skipping optimization that I mentioned at EuroLLVM talk.
Additionally, the file manager is still not reused by the threads as well.
