Really turn if-converter loose: 1. Consider all possible ifcvt cases at once. No longer restricted to bottom up iterative approach. 2. Sort all possible cases based on a cost function. Perform the most profitable ones first invalidate others that target the same blocks. 3. Fixed a number of bugs related to block duplication. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37613 91177308-0d34-0410-b5e6-96231b3b80d8
