r208453 added support for having sret on the second parameter. In that change, the code for copying sret into a virtual register was hoisted into the loop that lowers formal parameters. This caused a "Wrong topological sorting" assertion failure during scheduling when a parameter is passed in memory. This change undoes that by creating a second loop that deals with sret. I'm worried that this fix is incomplete. I don't fully understand the dependence issues. However, with this change we produce the same DAGs we used to produce, so if they are broken, they are just as broken as they have always been. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@208637 91177308-0d34-0410-b5e6-96231b3b80d8
