a DBG_LABEL or not. We want to fall back to the original way of emitting debug info when we're in -O0/-fast mode. - Add plumbing in to pass the "Fast" flag to places that need it. - XFAIL DebugInfo/deaddebuglabel.ll. This is finding 11 labels instead of 8. I need to investigate still. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@65367 91177308-0d34-0410-b5e6-96231b3b80d8
