lld: Add missing REQUIRES to tests

[grimar]

None of the rest ELF tests we have using "REQUIRES: x86_64". We already have "REQUIRES: x86" everywhere though. And ELF tests you fix in this patch have it too. So why do you want to add x86_64?

[ruiu]

Yeah, that was my question too. Can you enable only x86_64 without x86?

[tstellar]

My mistake. I had been working on the release_70 branch and did not realize the REQUIRES had been added to trunk when I rebased. Looks like this was fixed in r339253. I'll ask Hans to backport that to the stable branch.
