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.

And add build files for gtest.
With this, the build files for //lld are complete.

Also add a build file for llvm-lit, which in turn needs llvm/tools/llvm-config.
With this, check-lld runs and passes all of lld's lit tests. It doesn't run any
of its unit tests yet.
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-lld will build prerequisites if needed and run
the tests. The check-lld target never becomes clean and runs tests every time.
llvm-config's build file is a bit gnarly: Everything not needed to run tests is
basically stubbed out. Also, to generate LibraryDependencies.inc we shell out
to llvm-build at build-time. It would be much nicer to get the library
dependencies by using the dependency data the GN build contains
(http://llvm-cs.pcc.me.uk/gen/tools/llvm-config/LibraryDependencies.inc#1).

Adds a build file for clang-tblgen and an action for running it, and uses that
to process all the .td files in include/clang/Basic.
Also adds an action to write include/clang/Config/config.h and
include/clang/Basic/Version.inc.

(The previous commit of this contained unrelated changes, so I reverted the
whole previous commit and I'm now landing only what I intended to land.)

This is slightly involved, see the comments in the code.
The GN build now builds a functional lld!

Version.inc.in processing has a potentially interesting part which I've punted
on for now (LLD_REVISION and LLD_REPOSITORY are set to empty strings for now).
lld now builds in the gn build. But no symlinks to it are created yet, so it
can't be meaningfully run yet.
