We are not working on a DAG and I ran into a number of problems when I enabled the vectorizations of 'diamond-trees' (trees that share leafs). * Imroved the numbering API. * Changed the placement of new instructions to the last root. * Fixed a bug with external tree users with non-zero lane. * Fixed a bug in the placement of in-tree users. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182508 91177308-0d34-0410-b5e6-96231b3b80d8
