[Matthew Voss via Phabricator via llvm-commits]

@efriedma I'm not quite sure what that would look like here. Are you looking for something like the following?

  %a = alloca <7 x i1>, align 2
  store <7 x i1> undef, <7 x i1>* %a, align 2
  %0 = getelementptr inbounds <7 x i1>, <7 x i1>* %a, i64 0, i64 0
  %val0 = load i1, i1* %0, align 2
  %val1 = load i1, i1* %0, align 2
  br i1 %val0, label %cond.true, label %cond.false
