The new Darwin backend for LLD is now able to link reasonably large real-world programs on x86_64. For instance, we have achieved self-hosting for the X86_64 target, where all LLD tests pass when building lld with itself on macOS. As such, we would like to make it the default back-end. The new port is now named `ld64.lld`, and the old port remains accessible as `ld64.lld.darwinold` This [annoucement email][1] has some context. (But note that, unlike what the email says, we are no longer doing this as part of the LLVM 12 branch cut -- instead we will go into LLVM 13.) Numerous mechanical test changes were required to make this change; in the interest of creating something that's reviewable on Phabricator, I've split out the boring changes into a separate diff (D95905). I plan to merge its contents with those in this diff before landing. (@gkm made the original draft of this diff, and he has agreed to let me take over.)
