Basic rematerialization during splitting. Whenever splitting wants to insert a copy, it checks if the value can be rematerialized cheaply instead. Missing features: - Delete instructions when all uses have been rematerialized. - Truncate live ranges to the remaining uses after rematerialization. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118702 91177308-0d34-0410-b5e6-96231b3b80d8
