Create Generic DOTGraphTraits Printer/Viewer
Move the DOTGraphTraits dotty printer/viewer templates, that were developed for the dominance tree into their own header file. This will allow reuse in future passes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93632 91177308-0d34-0410-b5e6-96231b3b80d8
