Before this patch we relied on the order of phi nodes when we looked for phi nodes of the same type. This could prevent vectorization of cases where there was a phi node of a second type in between phi nodes of some type. This is important for vectorization of an internal graphics kernel. On the test suite + external on x86_64 (and on a run on armv7s) it showed no impact on either performance or compile time. radar://15024459 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@192537 91177308-0d34-0410-b5e6-96231b3b80d8
