Teach lib/VMCore/ConstantFold.cpp how to set the inbounds keyword and how to fold notionally-out-of-bounds array getelementptr indices instead of just doing these in lib/Analysis/ConstantFolding.cpp, because it can be done in a fairly general way without TargetData, and because not all constants are visited by lib/Analysis/ConstantFolding.cpp. This enables more constant folding. Also, set the "inbounds" flag when the getelementptr indices are one-past-the-end. llvm-svn: 81483
