[CMake] Add support for building the llvm test-suite as part of an LLVM build using clang and lld Summary: This patch adds a new CMake module for working with ExternalProjects. This wrapper for ExternalProject supports using just-built tools and can hook up dependencies properly so that projects get cleared out. The example usage here is for the llvm test-suite. In this example, the test-suite is setup as dependent on clang and lld if they are in-tree. If the clang or lld binaries change the test-suite is re-configured, cleaned, and rebuilt. This cleanup and abstraction wrapping ExternalProject can be extended and applied to other runtime libraries like compiler-rt and libcxx.

# llvm_ExternalProject_BuildCmd(out_var target)
# Utility function for constructing command lines for external project targets
[CMake] Make llvm_ExternalProject always call the build action This makes it so that when running 'ninja test-suite' from the top-level LLVM ninja build it *always* re-runs the ninja command in the test-suite directory. This mechanism is required because the top-level ninja file doesn't have a view into the subdirectory dependency tree, so it can't know what, if anything, needs to be rebuilt. llvm-svn: 265863
