Summary: This change spans both LLVM and compiler-rt, where we do the following: - Add XRay to the LLVMBuild system, to allow for distributing the XRay trace loading library along with the LLVM distributions. - Use `llvm-config` better in the compiler-rt XRay implementation, to depend on the potentially already-distributed LLVM XRay library. While this is tested with the standalone compiler-rt build, it does require that the LLVMXRay library (and LLVMSupport as well) are available during the build. In case the static libraries are available, the unit tests will build and work fine. We're still having issues with attempting to use a shared library version of the LLVMXRay library since the shared library might not be accessible from the standard shared library lookup paths. The larger change here is the inclusion of the LLVMXRay library in the distribution, which allows for building tools around the XRay traces and profiles that the XRay runtime already generates.
