r291284 added a nice mechanism to consistently pass CMake on/off toggles to
lit. This change uses it for LLVM_LIBXML2_ENABLED too (which was added around
the same time and doesn't use the new system yet).
Also alphabetically sort the list passed to llvm_canonicalize_cmake_booleans()
in llvm/test/CMakeLists.txt.
No intended behavior change.

The check-hwasan build files assert that current_os == "linux" || current_os ==
"android", so pull it in only there.
ar is unused on mac, so don't set it in the stage2 toolchain. (It'd be nicer to
use llvm-libtool on mac instead of host libtool, but llvm-libtool doesn't seem
to understand the -no_warning_for_no_symbols flag.)

llvm/tools sets LLVM_TOOL_LTO_BUILD to Off if LLVM_ENABLE_PIC=OFF, but that's
not visible in llvm/test.
r289662 added the llvm_tool_lto_build lit parameter, there the intent was to
use it with an explicit -DLLVM_TOOL_LTO_BUILD=OFF, which is visible globally.
On the review for that (D27739), a mild preference was expressed for using a
lit parameter over checking the existence of libLTO.dylib. Since that works
with the LLVM_ENABLE_PIC=OFF case too and since it matches what we do for the
gold plugin, switch to that approach.

The Android sanitizer tests are currently some of the most difficult
to run correctly, requiring at least 3 build directories which have
to be configured in just the right way and built in the correct order
(see e.g. [1] and the functions that it calls).
This patch adds a check-hwasan target which greatly simplifies running
the hwasan tests for gn users, taking advantage of its support for
multiple toolchains. With this the tests can be run simply by setting
an NDK path and running "ninja check-hwasan" with a compatible Android
device connected. The Linux/x86_64 and Android/aarch64 targets are
tested in parallel.

The path to the resource directory will end up being used in several
more places once the support for running check-hwasan lands. This
moves the definition to a central location so that it can be used
from those places.

This makes e.g. ToolChain::isCrossCompiling() in
clang/lib/Driver/ToolChain.cpp return the correct result
if the compiler was cross-compiled. This change also affects
llvm_default_target_triple, so cross-compiled compilers default to
targeting the cross-compilation target, which makes more sense than
the host that the compiler was compiled on.
This change will also be necessary in order for the correct triples
to appear in generated lit files for non-native targets.

This shortcut mechanism for creating types was added 10 years ago, but
has seen almost no uptake since then, neither internally nor in
external projects.
The very small number of characters saved by using it does not seem
worth the mental overhead of an additional type-creation API, so,
delete it.

The PowerPC target itself is similar to the X86 target in https://reviews.llvm.org/rL348903
The llvm-exegesis unittests bits are similar to the corresponding AArch64 in https://reviews.llvm.org/rL350499
The whole patch is very similar to the WebAssembly target being added in https://reviews.llvm.org/rL350628
Also add a dep from tools/llvm-exegesis/lib to the AArch64 subdir, which I
failed to do in r350499.
The motivation for this target is solely that it has a unit test and I want to
enable the GN<->CMake unittest syncing check for llvm.

This is slightly ugly for three reasons:
- The shlib needs to go next to the binary to be found on all platforms, so the
build files refer to target_out_dir
- The explicit -fPIC flag needed on the shared lib side, and the -rdynamic flag
needed on the host side, on Linux
- Plugins that refer to LLVM code and assume that the host will resolve them
don't work on Windows -- PluginsTests won't test anything on Windows (but
DynamicLibraryTests will, since the dll here doesn't call LLVM code)
If we get lots more of these plugin / plugin host targets it might make sense
to add a template for them. But for now, these are the last ones we need.
(We're at 6 plugin hosts, 2 of them tests, and at 6 shared libraries, 2 of them
tests as well. clang is a plugin host by default in the CMake build but not
(yet?) in the GN build.)

I'm pretty unhappy this patch: DebugInfoPDBTests uses an API that requires some
magic txt file to be next to the unit test executable that stores the absolute
path to the LLVM source root.
The choices here are:
1. Don't use the unittest() template for DebugInfoPDBTests and set output_dir
for unit tests in two places (the gni file for every test but this one, and the
BUILD.gn file for this specific test).
2. Add another unittest_foo() template variation for this one test.
I went with the former, and added a comment to the template to look out for
this.
(The CMake build has the same issue.)

Adds build files for //llvm/unittest/[A-D].
Also teach sync_source_lists_from_cmake.py to not complain about missing
BUILD.gn files for CMakeLists.txt files that just call add_subdirectory()
without calling add_.+_unittest, like e.g.
llvm/unittests/Target/CMakeLists.txt.
(Omits CodeGen/GlobalISel and DebugInfo/PDB because their build files are somewhat interesting, and this patch is already on the larger side.)

With this, check-llvm runs and passes all of clang's lit tests. It doesn't run
any of its unit tests yet.
This is the only change in the GN build patch series that needs a change to a
file outside of llvm/utils/gn: llvm/test/tools/llvm-config/booleans.test checks
the result of llvm-config --build-system for some reason, so I'm updating the
test to accept "gn" as valid output in addition to "cmake". (The alternative
would be to let the gn build self-identify as cmake, which seems worse.)
Like with check-clang and 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-llvm will
build prerequisites if needed and run the tests. The check-llvm target never
becomes clean and runs tests every time.
