2018-07-10[CMake] Add compiler-rt header files to the list of sources for targetsDan Liew
when building with an IDE so that header files show up in the UI. This massively improves the development workflow in IDEs. To implement this a new function `compiler_rt_process_sources(...)` has been added that adds header files to the list of sources when the generator is an IDE. For non-IDE generators (e.g. Ninja/Makefile) no changes are made to the list of source files. The function can be passed a list of headers via the `ADDITIONAL_HEADERS` argument. For each runtime library a list of explicit header files has been added and passed via `ADDITIONAL_HEADERS`. For `tsan` and `sanitizer_common` a list of headers was already present but it was stale and has been updated to reflect the current state of the source tree. The original version of this patch used file globbing (`*.{h,inc,def}`) to find the headers but the approach was changed due to this being a CMake anti-pattern (if the list of headers changes CMake won't automatically re-generate if globbing is used). The LLVM repo contains a similar function named `llvm_process_sources()` but we don't use it here for several reasons: * It depends on the `LLVM_ENABLE_OPTION` cache variable which is not set in standalone compiler-rt builds. * We would have to `include(LLVMProcessSources)` which I'd like to avoid because it would include a bunch of stuff we don't need.

2018-06-28Support for multiarch runtimes layoutPetr Hosek
This change adds a support for multiarch style runtimes layout, so in addition to the existing layout where runtimes get installed to: lib/clang/$version/lib/$os Clang now allows runtimes to be installed to: lib/clang/$version/$target/lib This also includes libc++, libc++abi and libunwind; today those are assumed to be in Clang library directory built for host, with the new layout it is possible to install libc++, libc++abi and libunwind into the runtime directory built for different targets. The use of new layout is enabled by setting the LLVM_ENABLE_RUNTIME_TARGET_DIR CMake variable and is supported by both projects and runtimes layouts. The runtimes CMake build has been further modified to use the new layout when building runtimes for multiple targets.

2018-06-27[CMake] Tidy up the organisation of compiler-rt when configured as a standaloneDan Liew
build with an IDE (e.g. Xcode) as the generator. Previously the global `USE_FOLDERS` property wasn't set in standalone builds leading to existing settings of FOLDER not being respected. In addition to this there were several targets that appeared at the top level that were not interesting and clustered up the view. These have been changed to be displayed in "Compiler-RT Misc". Now when an Xcode project is generated from a standalone compiler-rt build the project navigator is much less cluttered. The interesting libraries should appear in "Compiler-RT Libraries" in the IDE.

2018-06-07[CMake] Fix Libc++ Modules build.Eric Fiselier
When building the dylib, the C++ headers are fundamentally non-module. They require special versions of the headers in order to provide C++03 and legacy ABI definitions. This causes ODR issues when modules are enabled during both the build and the usage of the libc++ headers.
