Implement X / C1 / C2 folding Implement (setcc (shl X, C1), C2) folding. The second one occurs several dozen times in spec. The first was added just in case. :) These are tested by shift.ll:test2[12], and div.ll:test5 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16549 91177308-0d34-0410-b5e6-96231b3b80d8
