Also add a build file for clang/lib/ASTMatchers/Dynamic, which is only needed
by tests (and clang/tools/extra).
Also make llvm/utils/gn/build/sync_source_lists_from_cmake.py check that every
CMakeLists.txt file below {lld,clang}/unittests has a corresponding BUILD.gn
file, so we notice if new test binaries get added (since the failure mode for
missing GN build files for tests is just the tests silently not running in the
GN build).
Also add a unittest() macro for defining unit test targets, and add a lengthy
comment there about where the unit test binaries go and why.
With this, the build files for //clang are complete.

With this, check-clang runs and passes all of clang's lit tests. It doesn't run
any of its unit tests yet.
Like with check-lld, running just ninja -C out/gn will build all prerequisites
needed to run tests, but it won't run the tests (so that the build becomes
clean after one build). Running ninja -C out/gn check-clang will build
prerequisites if needed and run the tests. The check-clang target never becomes
clean and runs tests every time.
