LiveInterval: Document and enforce rules about empty subranges. Empty subranges are not allowed in a LiveInterval and must be removed instead: Check this in the verifiers, put a reminder for this in the comment of the shrinkToUses variant for a single lane and make it automatic for the shrinkToUses variant for a LiveInterval. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@242431 91177308-0d34-0410-b5e6-96231b3b80d8
