Summary:
Specify message levels in CMake. Prefer STATUS (stdout).
As the default message mode (i.e. level) is NOTICE in CMake, more then necessary messages get printed to stderr. Some tools, noticably ccmake treat this as an error and require additional confirmation and re-running CMake's configuration step.
This commit specifies a mode (either STATUS or WARNING or FATAL_ERROR) instead of the default.

When cross-compiling LLVM to android from Windows (for LLVMSupport), we would
attempt to execute `config.guess` to determine the host triple since
`CMAKE_SYSTEM_NAME` is not Windows and `CMAKE_C_COMPILER` will be set to GNU or
Clang. This will fail as `config.guess` is a shell script which cannot be
executed on Windows. Simply log a warning instead. The user can specify the
value for this instead in those cases.

Recommit of r361790 that was temporarily reverted in r361793 due to bot breakage.
Summary:
The following changes were required to fix these tests:
1) Change LLVM_ENABLE_PLUGINS to an option and move it to
llvm/CMakeLists.txt with an appropriate default -- which matches
the original default behavior.
2) Move the plugins directory from clang/test/Analysis
clang/lib/Analysis. It's not enough to add an exclude to the
lit.local.cfg file because add_lit_testsuites recurses the tree and
automatically adds the appropriate `check-` targets, which don't
make sense for the plugins because they aren't tests and don't
have `RUN` statements.
Here's a list of the `clang-check-anlysis*` targets with this
change:
```
$ ninja -t targets all| sed -n "s/.*\/\(check[^:]*\):.*/\1/p" | sort -u | grep clang-analysis

3) Simplify the logic and only include the subdirectories under
clang/lib/Analysis/plugins if LLVM_ENABLE_PLUGINS is set.

LLVM CMake build already uses libtool instead of ar when building
for Apple platform and we should be using the same when building
runtimes. To do so, this change extracts the logic for finding
libtool into a separate file and then uses it from both the LLVM

CMake always uses absolute file paths in the generated compiler
invocation which results in absolute file paths being embedded in debug
info. This is undesirable when building a toolchain e.g. on bots as the
debug info may embed the bot source checkout path which is meaningless
anywhere else.
This change introduces the LLVM_USE_RELATIVE_PATHS_IN_DEBUG_INFO which uses
-fdebug-prefix-map (where supported) options to rewrite paths embedded
into debug info with relative ones. Additionally, LLVM_SOURCE_PREFIX can
be used to override the path to source directory with a different one.

Summary:
Clangd's framework is assembled by copying binaries from the lib and bin directories into a bundle shape. This results in an invalid bundle code signature because the signature only applies to the binaries not the resources.
This patch adds two new options to `llvm_codesign` to enable re-signing the library and XPC service as bundles.
The `BUNDLE_PATH` option allow specifying an explicit path to codesign, which enables signing bundles which aren't generated using CMake's `FRAMEWORK` or `BUNDLE` target properties.
The `FORCE` option allows re-signing binaries that have already been signed. This is required for how clangd exposes the clangd library and tools as both XPC and non-XPC services using the same binary.

Summary:
For the most part this consists of replacing ${LLVM_TARGETS_TO_BUILD} with
some combination of AllTargets* so that they depend on specific components
of a target backend rather than all of it. The overall effect of this is
that, for example, tools like opt no longer falsely depend on the
disassembler, while tools like llvm-ar no longer depend on the code
generator.
There's a couple quirks to point out here:
* AllTargetsCodeGens is a bit more prevalent than expected. Tools like dsymutil
seem to need it which I was surprised by.
* llvm-xray linked to all the backends but doesn't seem to need any of them.
It builds and passes the tests so that seems to be correct.
* I left gold out as it's not built when binutils is not available so I'm
unable to test it

Summary:
clang and newer versions of ninja use high-resolutions timestamps, but
older versions of libtool on Darwin don't, so the archive will often
get an older timestamp than the last object that was added or updated.
To fix this, we add a custom command to touch the archive after it's
been built so that ninja won't rebuild it unnecessarily the next time
it's run.

- Stop passing -gwarf to the compiler in sanitizer options when lld is

Summary: When libc++ is used to build CLANG, its XRay libraries libclang_rt.xray-*.a have dependencies on libc++. Therefore, libc++ is needed to link and run XRay test cases. For Linux -rpath is also needed to specify where to load libc++. This change sets macro LLVM_LIBCXX_USED to 1 if libc++ is actually used in the build. XRay tests then check the flag and add -L<llvm_shlib_dir> -lc++ and -Wl,-rpath=<llvm_shlib_dir> if needed.

Summary:
There is a bug in add_tablegen which causes cmake to fail with the following
error message if LLVM_TABLEGEN is set.
CMake Error at cmake/modules/TableGen.cmake:147 (add_dependencies):
The dependency target "LLVM-tablegen-host" of target "CLANG-tablegen-host"
does not exist.
Call Stack (most recent call first):
tools/clang/utils/TableGen/CMakeLists.txt:3 (add_tablegen)
The issue happens because setting LLVM_TABLEGEN causes cmake to skip generating
the LLVM-tablegen-host target. As a result, a non-existent target was added for
CLANG-tablegen-host causing cmake to fail.
In order to fix this issue, this patch adds a guard to check the validity of the
dependency target before adding it as a dependency.

Instead of duplicating functionality for building native versions of
tblgen and llvm-config, add a function to set up a native tool build.
This will also be used for llvm-nm in a follow-up.
This should be NFC for tblgen, besides the slightly different COMMENT
for the custom command (it'll display the tablegen target name instead
of always saying TableGen). For the native llvm-config, it's a behavior
change in that we'll use llvm_ExternalProject_BuildCmd instead of
constructing the build command manually, always build in Release, and
reference the correct binary path for multi-config generators. I believe
all of these changes to be bug fixes.
