Duncan Sands ff10341183 Fix a layering violation: hasConstantValue, which is part of the PHINode ... class, uses DominatorTree which is an analysis. This change moves all of the tricky hasConstantValue logic to SimplifyInstruction, and replaces it with a very simple literal implementation. I already taught users of hasConstantValue that need tricky stuff to use SimplifyInstruction instead. I didn't update InlineFunction because the IR looks like it might be in a funky state at the point it calls hasConstantValue, which makes calling SimplifyInstruction dangerous since it can in theory do a lot of tricky reasoning. This may be a pessimization, for example in the case where all phi node operands are either undef or a fixed constant. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119459 91177308-0d34-0410-b5e6-96231b3b80d8		2010-11-17 04:30:22 +00:00
