While we don't build this target explicitly in our toolchain, it is built when running tests via `stage2-check-clang`. Is there perhaps a simple cmake flag that allows us to not run clang-repl tests so we don't build it?

@leonardchan, @phosek, I am not aware of such flag. Do you know how much memory does LTO + clang-repl consume and would it make sense to ping some of the LTO folks for their advice?
