Post-RA sched strategy and scheduling instruction annotations for z196, zEC12 and z13. This scheduler optimizes decoder grouping and balances processor resources (including side steering the FPd unit instructions). The SystemZHazardRecognizer keeps track of the scheduling state, which can be dumped with -debug-only=misched. Reviers: Ulrich Weigand, Andrew Trick. https://reviews.llvm.org/D17260 llvm-svn: 284704
