[Xin Tong]

what does JustRef mean in LLVM ? i fgrep over the source code and did not
see any comment on it.

bash-4.1$ opt -S -basicaa -count-aa -gvn  def.ll -o def.opt.ll
JustRef:  Ptr: [18446744073709551615B] i32* %p  <->  call void @hold(i32
%sub)
May alias:      [18446744073709551615B] i32* %q, [18446744073709551615B]
