SROA. The crux of the issue is that now we track uses of a partition of the alloca in two places: the iterators over the partitioning uses and the previously collected split uses vector. We weren't accounting for the fact that the split uses might invalidate integer widening in ways other than due to their width (in this case due to being volatile). Further reduced testcase added to the tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186655 91177308-0d34-0410-b5e6-96231b3b80d8
