Move lib/Analysis/DebugInfo.cpp to lib/VMCore/DebugInfo.cpp and include/llvm/Analysis/DebugInfo.h to include/llvm/DebugInfo.h. The reasoning is because the DebugInfo module is simply an interface to the debug info MDNodes and has nothing to do with analysis. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159312 91177308-0d34-0410-b5e6-96231b3b80d8
