[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).

[CMake] Workflow improvements to PGO generation This patch adds a few new convenience options used by the PGO CMake cache to setup options on bootstrap stages. The new options are: PGO_INSTRUMENT_LTO - Builds the instrumented and final builds with LTO PGO_BUILD_CONFIGURATION - Accepts a CMake cache script that can be used for complex configuration of the stage2-instrumented and stage2 builds. The patch also includes a fix for bootstrap dependencies so that the instrumented LTO tools don't get used when building the final stage, and it adds distribution targets to the passthrough. llvm-svn: 278862

[CMake] Adding toolchain targets to PGO and Apple CMake caches The Xcode toolchain targets are useful on OS X hosts because you can construct and install multiple toolchians that can be used seamlessly. llvm-svn: 278987
