Point Linux users towards LLDB for their REPL.

The Swift compiler has a bare-bones integrated REPL for testing purposes,
but it hasn't been ported to any platforms besides OS X. The real REPL is
part of LLDB and works on both OS X and Linux.

I've already seen two questions about this error message, so at least
pointing people towards LLDB is probably a good idea.

No functionality change.
