FastIsel: take care to update iterators when removing instructions. We keep a few iterators into the basic block we're selecting while performing FastISel. Usually this is fine, but occasionally code wants to remove already-emitted instructions. When this happens we have to be careful to update those iterators so they're not pointint at dangling memory. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@349365 91177308-0d34-0410-b5e6-96231b3b80d8
