Justin Bogner 5ca4d5f5fe cmake: Don't try to install exports if there aren't any
When using LLVM_DISTRIBUTION_COMPONENTS, it's possible for clang's
export list to be empty. If this happens the install(EXPORTS) command
will fail, but since there isn't anything to install anyway we really
just want to skip it.

Justin Bogner 66b326bc55 cmake: Support exports correctly with LLVM_DISTRIBUTION_COMPONENTS
We need to apply the same export logic in clang as in llvm for
LLVM_DISTRIBUTION_COMPONENTS, or the clang exports will be invalid
when we use this config.

This makes using distribution components without setting
LLVM_TOOLCHAIN_ONLY=On work correctly.

Michael Gottesman 66cc2d5210 [cmake] Follow LLVM's lead in creating exported tool targets for clang tools.
This is needed by downstream projects such as swift to get proper cmake
dependency information for LLVM/Clang targets.

A few months ago I added support for exporting this information for Clang
libraries. In order to be incremental, I did not add support for exporting clang
tools as well at that time. Now such support is needed, so I am committing this
incremental code.

Michael Gottesman eb396a6cbf Add CLANG_BUILD_TOOLS as a clang counterpart for LLVM_BUILD_TOOLS
LLVM_BUILD_TOOLS is a boolean variable that controls whether or not generated
targets for llvm tools are built by the "all" target. CLANG_BUILD_TOOLS is an
analogous variable for clang targets.

This is useful functionality for selectively disabling the building of clang
targets by default to speed up builds.

In terms of implementation, I just followed the model of LLVM's implementation
of this functionality.

Michael Gottesman ca589ccb02 Move add_clang_* entry points from the main clang CMakeLists.txt to cmake/modules/AddClang.cmake.
This matches how LLVM has its cmake files organized and is cleaner than just
shoving this business logic into the main CMakeLists.txt.
