Integrate libiomp CMake into LLVM CMake build system. This patch integrates the libiomp CMake build system into the LLVM CMake build system so that users can checkout libiomp into the projects directory of llvm and build llvm,clang, and libiomp all together. These changes specifically introduce a new install target which will put libraries and headers into the correct locations when either a standalone build or part of llvm. The copy_recipe() method has been removed in favor of the POST_BUILD method to move headers into the exports subdirectory. And lastly, the MicroTests.cmake file was refactored which led to simpler target dependencies and a new target, make libiomp-micro-tests, which performs the 5 small tests (test-relo, test-touch, etc.) when called. llvm-svn: 236534

[CMake] Introduce OPENMP_LLVM_TOOLS_DIR This will be used in a later patch to find additional LLVM tools for tests and enables reusability for libomptarget that is currently under review. Differential Revision: http://reviews.llvm.org/D16713 llvm-svn: 259876

[CMake] Disallow direct configuration As a first step, this allows us to generalize the detection of standalone builds and make it fully compatible when building in llvm/runtimes/ which automatically sets OPENMP_STANDLONE_BUILD.

libomptarget: Disable on Win32 It's not supported, and currently breaks the weekly LLVM snapshot builds. Differential Revision: https://reviews.llvm.org/D29801 llvm-svn: 294758

[CMake] Disable building libomptarget and add CMake switch Introduce OPENMP_ENABLE_LIBOMPTARGET which defaults to OFF at the moment. libomptarget is not yet ready for prime time: - Offloading to NVIDIA GPUs is not completed yet (compiler, device RTL) - The generic ELF plugin for offloading to the host (meant for testing) uses a single instance of the OpenMP runtime (libomp). That is why omp_is_initial_device() returns 1 which makes the tests fail. Because of these reasons, we want to disable building (and testing!) for release 5.0.

[CMake] Re-enable libomptarget and restrict tests to Clang 6.0.0 We have just fixed the codegen of omp_is_initial_device() to reliably work when offloading to the same device, see commit r316001. This fixes the failing tests that were the reason why we disabled the library for 5.0. Differential Revision: https://reviews.llvm.org/D39052 llvm-svn: 318847

# Currently libomptarget cannot be compiled on Windows or MacOS X.
# Since the device plugins are only supported on Linux anyway,
# there is no point in trying to compile libomptarget on other OSes.
