Reinteroduce the code for moving ARGUMENTS back to the top of the basic block. While the ARGUMENTS physical register prevents sinking and scheduling from moving them, it does not appear to be sufficient to prevent SelectionDAG from moving them down in the initial schedule. This patch introduces a patch that moves them back to the top immediately after SelectionDAG runs. This is still hopefully a temporary solution. http://reviews.llvm.org/D14750 is one alternative, though the review has not been favorable, and proposed alternatives are longer-term and have other downsides. This fixes the main outstanding -verify-machineinstrs failures, so it adds -verify-machineinstrs to several tests. Differential Revision: http://reviews.llvm.org/D15377 llvm-svn: 255125
