Peter Collingbourne b6e7ff238c Prevent Constant Folding From Optimizing inrange GEP ... This patch does the following things: 1. update SymbolicallyEvaluateGEP so that it bails out if it cannot preserve inrange arribute; 2. update llvm/test/Analysis/ConstantFolding/gep.ll to remove UB in it; 3. remove inaccurate comment above ConstantFoldInstOperandsImpl in llvm/lib/Analysis/ConstantFolding.cpp; 4. add a new regression test that makes sure that no optimizations change an inrange GEP in an unexpected way.
