Implement a new DecomposeGEPExpression method, which decomposes a GEP into a list of scaled offsets. Use this to eliminate some previous ad-hoc code which was subtly broken (it assumed all Constant*'s were non-zero, but strange constant express could be zero). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89915 91177308-0d34-0410-b5e6-96231b3b80d8
