instructions to reoptimize. Exploit this to more systematically eliminate dead instructions (this isn't very useful in practice but is convenient for analysing some testcase I am working on). No need for WeakVH any more: use an AssertingVH instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158073 91177308-0d34-0410-b5e6-96231b3b80d8
