integers in that the code to handle split alloca-wide integer loads or stores doesn't come first. It should, for the same reasons as with integers, and the PR attests to that. Also had to fix a busted assert in that this test case also covers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167051 91177308-0d34-0410-b5e6-96231b3b80d8
