[clang-scan-deps] Implementation of dependency scanner over minimized sources 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.

Reland "[clang-scan-deps] Add support for clang-cl" 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 patch adds support for clang-cl command options. Differential Revision: https://reviews.llvm.org/D92191
