Add DAGCombiner load combine tests for partially available values If some of the trailing or leading bytes of a load combine pattern are zeroes we can combine the pattern to a load + zext and shift. Currently we don't support it, so the tests check the current codegen without load combine. This change will make the patch to support this kind of combine a bit more clear. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@294591 91177308-0d34-0410-b5e6-96231b3b80d8
