Petr Hosek 427b895e2f [CMake] Link static libunwind and libc++abi into libc++ in Fuchsia toolchain
When building libc++ for Fuchsia, we want to distribute shared libc++,
libc++abi and libunwind as separate libraries, but for static versions
we would like to link all of them into libc++ so -lc++ flag has the same
effect whether shared or static library is being used.

Petr Hosek 2423c16935 [CMake] Use explicit targets for building Linux runtimes
Previously we were using default logic when building Linux runtimes
in Fuchsia toolchain, but that leads to various issues due to how
the CMake logic in compiler-rt for determining the platform support
is implemented. With this change, we will use explicit target for
every provided Linux sysroot.

Petr Hosek 7636840b87 [CMake] Support passing FUCHSIA_SDK as the only variable
Now that the structure of Fuchsia SDK has been formalized, we no
longer need to pass all the different CFLAGS/LDFLAGS to the CMake
build separately, we can simply set the FUCHSIA_SDK variable and
derive all the necessary variables from that one inside the cache
file.

It's used to determine whether terminal supports colors, but within LLVM
it's only used in handful of places and in Clang it's only used in AST
dumper, otherwise Clang relies on the -fcolor-diagnostics flag which we
pass explicitly from our build system anyway. This eliminates one of the
shared libraries dependencies making the toolchain less reliant on the
host environment.

Chris Bieneman ba83735b2f [CMake] Updating Apple build configurations
This updates Apple build configurations to adapt to r263566 & r263570, which added a PACKAGE_VENDOR variable.

Chris Bieneman cc2aded1ff [CMake] Updating Apple Clang CMake caches
This is a big update that gets the public configurations more in line with the ones we're actually using internally to ship Clang in Xcode.

From here forward I expect most of the changes in these files to be incremental as the changes get made internally.

Chris Bieneman 33b41961c3 [CMake] Only configure Native target in stage 1, configure all in other stages
This patch causes the 3-stage build pipeline to only build a host compiler in the first stage, and to build all targets for subsequent stages. The host target is determined via the Native target specifier added in r262070.

Chris Bieneman 7590a1ee61 [CMake] For multi-stage builds to be deterministic we need to disable timestamps.
Duh! With this change I've verified -O3 builds are deterministic.

Chris Bieneman a0a0317dbc [CMake] Fixing the 3-stage cmake cache.
I had hoped this would work from a single cache file, but turns out there is a bug I can't quite figure out relating to passing list arguments to recursive CMake invocations.

This change works around that.

Chris Bieneman 6ced921f8c [CMake] Providing a CMake cache for 3-stage builds
This cache file can be used to generate a 3-stage clang build. You can configure using the following CMake command:

cmake -C <path to clang>/cmake/caches/3-stage.cmake -G Ninja <path to llvm>

You can then run "ninja stage3-clang" to build stage1, stage2 and stage3 clangs.

This is useful for finding non-determinism the compiler by verifying that stage2 and stage3 are identical.

Chris Bieneman b2920a779c [CMake] Support a simple case for bootstrap builds to generate PGO data
Summary:
This patch adds support for the clang multi-stage bootstrapping to support PGO profdata generation, and can build a 2 or 3 stage compiler.

With this patch applied you can configure your build directory with the following invocation of CMake:

cmake -G <generator> -C <path_to_clang>/cmake/caches/PGO.cmake <source dir>

After configuration the following additional targets will be generated:

stage2-instrumented:
Builds a stage1 x86 compiler, runtime, and required tools (llvm-config, llvm-profdata) then uses that compiler to build an instrumented stage2 compiler.

stage2-instrumented-generate-profdata:
Depends on "stage2-instrumented" and will use the instrumented compiler to generate profdata based on the training files in <clang>/utils/perf-training

stage2:
Depends on "stage2-instrumented-generate-profdata" and will use the stage1 compiler with the stage2 profdata to build a PGO-optimized compiler.

stage2-check-llvm:
Depends on stage2 and runs check-llvm using the stage3 compiler.

stage2-check-clang:
Depends on stage2 and runs check-clang using the stage3 compiler.

stage2-check-all:
Depends on stage2 and runs check-all using the stage3 compiler.

stage2-test-suite:
Depends on stage2 and runs the test-suite using the stage3 compiler (requires in-tree test-suite).

Chris Bieneman ea7ecde87c [CMake] Add cache scripts for Apple-style clang builds.
Summary:
These CMake cache scripts are my first pass at replicating Apple's packaging logic from autoconf. They can be used on any Darwin machine to approximate an Apple Clang build.

The included README file includes documentation and a sample CMake invocation.
