IR: Fix a use-after-free in RAUW Happened pretty commonly during `LLVMContext` teardown when `clang -g` hit an error. This fixes the use-after-free. Next I'll clean up teardown so that it's not RAUW'ing when metadata-tracked values are deleted (only really causes a problem if the graph is mid-construction when teardown starts, but it's still unnecessary work). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@226029 91177308-0d34-0410-b5e6-96231b3b80d8
