[lld-macho] Remove old macho darwin lld

[keith]

Summary

During the llvm round table it was generally agreed that the newer macho
lld implementation is feature complete enough to replace the old
implementation entirely. This will reduce confusion for new users who
aren't aware of the history.

I chose to remove the darwinnew / darwinold symlinks here as well. Let me know if you all think we should leave those around for a while for some reason

[int3]

lgtm. Could you make a post to llvm-dev before landing this? Thanks!

Consider moving the clang driver change to a separate change so that the removal is a more pure file deletion (other than some build system changes)

Fair enough, I'll submit as a follow up

Just wondering, can't we delete this too?
