Chris Bieneman 3eaf5dc052 [Apple Clang] Expose llvm-config from stage2 builds in stage1
This exposes the stage2-llvm-config target though the stage1 build configuration.

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 b79e55577e [CMake] Updating caches README with explanations of useful cache files.
This is in response to silvas' post-commit suggestion.

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.
