[CMake] Add lto subdirectory explicitly.
This is required because ExternalProject_Add requires all targets specified in the DEPENDS argument must exist before calling ExternalProject_Add. I have a follow-up patch to clang that enables using the just-built libLTO in bootstrap builds, so we need to be able to add the LTO target as a dependency in clang. llvm-svn: 247316
