[clang] e4b3fc1 - Get rid of -Wunused warnings in release build, NFC.

[David Blaikie via cfe-commits]

I don't think the comment's adding value here - it should be fairly
clear from the context that the whole loop only exists for some
assertions.

Also: Could you remove the "(void)" casts now that the whole thing's
wrapped in NDEBUG?

(an alternative way of phrasing this that doesn't require the #ifdef
would be using nested llvm::all_of calls, but that would mean the
assertion firing wouldn't point to a particular mismatched pair, just
that overall the data structures were mismatched - if you think that
this isn't especially likely/wouldn't be super hard to debug with
that, maybe the assert would be more compact/tidier?

assert(llvm::all_of(Dependencies, [&](const auto &DepPair) {
  return llvm::all_of(WeakDependencies, [&](const auto &WeakDepPair) {
    return WeakDepPair != DepPair && WeakDepPair.first !=
DepPair.second && WeakDepPair.second != DepPair.second;
  }
}) && "...");
