Summary:
Previously, write_cmake_config.py would raise an error while printing
the error, because `leftovers` in "'\n'.join(leftovers)" is a tuple.

Most significantly, this makes bin/llvm-lit executable so that it
can be run in the usual way.

I got that wrong once while locally while working on check-llvm.

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).

Tweak write_cmake_config.py to also handle variable references looking @FOO@
(matching CMake's configure_file() function), and make it replace '\' 'n' in
values with a newline literal since there's no good portable way of passing a
real newline literal on a command line.
Use that to process all the .def.in files in llvm/include/Config and add
llvm/lib/Target/BUILD.gn, which (indirectly, through llvm-c/Target.h) includes
them.

No behavior change, just makes the script match the other scripts in
llvm/utils/gn/build.

Before, #cmakedefine FOO resulted in #define FOO with a trailing space if FOO
was set to something truthy. Make it so that it's just #define FOO without a
trailing space.
No functional difference.

Before, the script had a bunch of special cases for #cmakedefine and
#cmakedefine01 and then did general variable substitution. Now, the script
always does general variable substitution for all lines and handles the special
cases afterwards.
This has no observable effect for the inputs we use, but is easier to explain
and slightly easier to implement.
Also mention to link to CMake's configure_file() in the docstring.
(The new behavior doesn't quite match CMake on lines like #cmakedefine ${FOO},
but nobody does that.)

Also add a shebang line to write_cmake_config.py.

file for llvm/lib/Support.
The comments at the top of
llvm/utils/gn/secondary/llvm/include/llvm/Config/BUILD.gn and
llvm/utils/gn/build/write_cmake_config.py should explain the main bits
happening in this patch. The main parts here are that these headers are
generated at build time, not gn time, and that currently they don't do any
actual feature checks but just hardcode most things based on the current OS,
which seems to work well enough. If this stops being enough, the feature checks
should each be their own action writing the result to somewhere, and the config
write step should depend on those checks (so that they can run in parallel and
as part of the build) -- utils/llvm/gn/README.rst already has some more words
on that in "Philosophy".
(write_cmake_config.py is also going to be used to write clang's
clang/include/clang/Config/config.h)
This also adds a few files for linking to system libraries in a consistent way
if needed in llvm/utils/gn/build/libs (and moves pthread to that model).0
I'm also adding llvm/utils/gn/secondary/llvm/lib/Target/targets.gni in this
patch because $native_arch is needed for writing llvm-config.h -- the rest of
it will be used later, when the build files for llvm/lib/Target get added. That
file describes how to select which archs to build.
As a demo, also add a build file for llvm-undname and make it the default build
target (it depends on everything that can currently be built).
