The Apple stage2 build should include compiler-rt iOS libraries and be built with the stage2 compiler. This matches Apple's production clang builds.

This exposes the stage2-llvm-config target though the stage1 build configuration.

This updates Apple build configurations to adapt to r263566 & r263570, which added a PACKAGE_VENDOR variable.

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.

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.

ClangConfig requires LLVMConfig, so add find_package call in
ClangConfig so find_package(clang REQUIRED CONFIG) will just work.  This
makes it easier for cmake based projects to use clang, e.g., tools using
ClangTooling.

Duh! With this change I've verified -O3 builds are deterministic.

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.

This is in response to silvas' post-commit suggestion.

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.

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).

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.

Installing <prefix>/share/clang/cmake/ClangConfig.cmake makes CMake's
builtin find_package() utility work with Clang. This also allows
downstream consumers of Clang to statically link against libraries like
clangAST and have that pull in dependencies like clangBasic and
LLVMSupport.
