Fix LSR: don't normalize quadratic recurrences. Partial fix for PR17459: wrong code at -O3 on x86_64-linux-gnu (affecting trunk and 3.3) ScalarEvolutionNormalization was attempting to normalize by adding and subtracting strides. Chained recurrences don't work that way. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193437 91177308-0d34-0410-b5e6-96231b3b80d8
